[PATCH v2 0/2] ARM: dts: at91: Fixes for AT91SAM9G20-EK DTS

The DT description for the audio subsystem on the AT91SAM9G20-EK
reference board is a bit bitrotted, the clocking for the WM8731 audio
CODEC is not described. Previously this was handled in the machine
driver but at some point in the transition to the common clock framework
that code was broken and rendered mostly redundant so the first patch
adds a mapping of the MCLK on the CODEC which is used via existing code
in it's driver.

We also have some warnings on the WM8731, EEPROM and the MMC from the
regulator framework since the supplies on the board aren't described.
These don't fundamentally matter since they are fixed voltage regulators
and not controlled by software at runtime but it's nicer to fix them.

v2:
 - Rebase onto v5.18-rc1.
 - Also cover the serial EEPROM supply which is requested by that driver.
