[twsi] Make extres/clk part conditional based on the EXT_RESOURCES option value

This should fix kernel build for ARMADA38X and possibly some other ARM configs

allwinner: clk: prediv_mux: Init the current parent

Do not init the first parent but read the clock register to find
it's current parent and init this one.

r347490:
allwinner: clk: sun8i_r: Correct resets

The i2c reset wasn't defined and some bits where wrong, correct them.

r347491:
twsi: Calculate the clock param based on the bus frequency

Instead of precalculating the different speed, respect the bus frequency
and calculate the clock register parameter based on it.
If the platform didn't register the core clk, fallback on the precomputed
values (This is likely do be the case on Marvell boards).

r347512:
arm: allwinner: aw_clk_nm: Don't reparent the clock if we didn't ask

When looking for the best frequency don't change the clock parent if the
clock wasn't configured to do that.

arm64: marvell: Add driver for Marvell Ap806 System Controller

The first two clocks are for the clusters and their frequencies can be
found reading a register. Then a fixed 1200Mhz clock is present and two
fixed clocks, 'mss' which is 1200 / 6 and 'sdio' which is 1200 / 3.

twsi: Add interrupt mode

Add the ability to use interrupts for i2c message.
We still use polling for early boot i2c transfer (for PMIC
for example) but as soon as interrupts are available use them.
On Allwinner SoC >A20 is seems that polling mode is broken for some
reason, this is now fixed by using interrupt mode.
For Allwinner also fix the frequency calculation, the one in the code
was for when the APB frequency is at 48Mhz while it is at 24Mhz on most
(all?) Allwinner SoCs. We now support both cases.

While here add more debug info when it's compiled in.

Tested On: A20, H3, A64

Define macros making it easier to define bus-specific pnpinfo for FDT systems.

Pnpinfo is bus-specific and requires the bus name. The FDTCOMPAT_PNP_INFO()
macro makes it easier to define new FDT-based pnpinfo for busses other than
simplebus.

Differential Revision: https://reviews.freebsd.org/D20382

r348170:
Add pnpinfo for icee(4) on fdt systems.

r348172:
Use the new FDTCOMPAT_PNP_INFO() macro to define SPIBUS_FDT_PNP_INFO().
Also rename SPIBUS_PNP_INFO -> SPIBUS_FDT_PNP_INFO because there could be
other kinds of pnpinfo for other (non-fdt) bus attachments.

r348173:
Rename IICBUS_FDT_PNPINFO -> IICBUS_FDT_PNP_INFO because all the other
existing pnpinfo-related macros right now use PNP_INFO, not PNPINFO.

r348183:
Add pnpinfo.

r348184:
Add pnpinfo to all i2c drivers that have FDT compat data.
