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/'

clk: keystone: Add new driver to handle syscon based clocks

On TI's AM654/J721e SoCs, certain clocks can be gated/ungated by setting
a single bit in SoC's System Control Module registers. Sometime more
than one clock control can be in the same register.

Add a driver to support such clocks using syscon framework. Driver
currently supports controlling EHRPWM's TimeBase clock(TBCLK) for AM654
SoC.

clk: keystone: sci-clk: probe clocks from DT instead of firmware

Probing all the available clocks from the PM firmware takes quite a lot
of time, increasing boot time. Instead, implement functionality that
parses only the used clocks from DT, and registers these to clock core.
This way, the boot time is greatly improved.

Additionally, provide a Kconfig option for parsing all the clocks from
firmware, if someone requires this. It is mostly useful as a debugging
functionality if we want to inspect the whole clock tree.

clk: keystone: TI_SCI_PROTOCOL is needed for clk driver

CONFIG_COMPILE_TEST allows building a configuration without
TI_SCI_PROTOCOL, which then fails to link:

drivers/clk/keystone/sci-clk.o: In function `ti_sci_clk_probe':
sci-clk.c:(.text.ti_sci_clk_probe+0x4c): undefined reference to `devm_ti_sci_get_handle'

This makes it a hard dependency. Right now, that means we can't
actually compile-test the driver unless ARCH_KEYSTONE is set as
well, but we can fix that by allowing TI_MESSAGE_MANAGER to
be selected for COMPILE_TEST as well.

clk: keystone: Add sci-clk driver support

In K2G, the clock handling is done through firmware executing on a
separate core. Linux kernel needs to communicate to the firmware
through TI system control interface to access any power management
related resources, including clocks.

The keystone sci-clk driver does this, by communicating to the
firmware through the TI SCI driver. The driver adds support for
registering clocks through DT, and basic required clock operations
like prepare/get_rate, etc.
