can: gs_usb: convert to NAPI/rx-offload to avoid OoO reception

The driver used to pass received CAN frames/skbs to the network stack
with netif_rx(). In netif_rx() the skbs are queued to the local CPU.
If IRQs are handled in round robin, OoO packets may occur.

To avoid out-of-order reception convert the driver from netif_rx() to
NAPI.

For USB devices with timestamping support use the rx-offload helper
can_rx_offload_queue_timestamp() for the RX, and
can_rx_offload_get_echo_skb_queue_timestamp() for the TX path. Devices
without timestamping support use can_rx_offload_queue_tail() for RX,
and can_rx_offload_get_echo_skb_queue_tail() for the TX path.

can: usb: f81604: add Fintek F81604 support

This patch adds support for Fintek USB to 2CAN controller.

Changelog:
v7: https://lore.kernel.org/all/[email protected]
1. Fix consistency of coding style for "break" in f81604_register_urbs().
2. Remove goto statement in f81604_open().

v6: https://lore.kernel.org/all/[email protected]
1. Remove non-used define and change constant mask to GENMASK().
2. Move some variables declaration from function start to block start.
3. Move some variables initization into declaration.
4. Change variable "id" in f81604_start_xmit() only for CAN ID usage.

v5: https://lore.kernel.org/all/[email protected]
1. Change all u8 *buff to struct f81604_int_data/f81604_can_frame.
2. Change all netdev->dev_id to netdev->dev_port.
3. Remove over design for f81604_process_rx_packet(). This device only
report a frame at once, so the f81604_process_rx_packet() are reduced
to process 1 frame.

v4: https://lore.kernel.org/all/[email protected]
1. Remove f81604_prepare_urbs/f81604_remove_urbs() and alloc URB/buffer
dynamically in f81604_register_urbs(), using "urbs_anchor" for manage
all rx/int URBs.
2. Add F81604 to MAINTAINERS list.
3. Change handle_clear_reg_work/handle_clear_overrun_work to single
clear_reg_work and using bitwise "clear_flags" to record it.
4. Move __f81604_set_termination in front of f81604_probe() to avoid
rarely racing condition.
5. Add __aligned to struct f81604_int_data / f81604_sff / f81604_eff.
6. Add aligned operations in f81604_start_xmit/f81604_process_rx_packet().
7. Change lots of CANBUS functions first parameter from struct usb_device*
to struct f81604_port_priv *priv. But remain f81604_write / f81604_read
/ f81604_update_bits() as struct usb_device* for
__f81604_set_termination() in probe() stage.
8. Simplify f81604_read_int_callback() and separate into
f81604_handle_tx / f81604_handle_can_bus_errors() functions.

v3: https://lore.kernel.org/all/[email protected]
1. Change CAN clock to using MEGA units.
2. Remove USB set/get retry, only remain SJA1000 reset/operation retry.
3. Fix all numberic constant to define.
4. Add terminator control. (only 0 & 120 ohm)
5. Using struct data to represent INT/TX/RX endpoints data instead byte
arrays.
6. Error message reports changed from %d to %pe for mnemotechnic values.
7. Some bit operations are changed to FIELD_PREP().
8. Separate TX functions from f81604_read_int_callback().
9. cf->can_id |= CAN_ERR_CNT in f81604_read_int_callback to report valid
TX/RX error counts.
10. Move f81604_prepare_urbs/f81604_remove_urbs() from CAN open/close() to
USB probe/disconnect().
11. coding style refactoring.

v2: https://lore.kernel.org/all/[email protected]
1. coding style refactoring.
2. some const number are defined to describe itself.
3. fix wrong usage for can_get_echo_skb() in f81604_write_bulk_callback().

treewide: replace '---help---' in Kconfig files with 'help'

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

The UCAN driver supports the microcontroller-based USB/CAN
adapters from Theobroma Systems. There are two form-factors
that run essentially the same firmware:

* Seal: standalone USB stick ( https://www.theobroma-systems.com/seal )

* Mule: integrated on the PCB of various System-on-Modules from
Theobroma Systems like the A31-µQ7 and the RK3399-Q7
( https://www.theobroma-systems.com/rk3399-q7 )

The USB wire protocol has been designed to be as generic and
hardware-indendent as possible in the hope of being useful for
implementation on other microcontrollers.
