[PATCH 1/1] ARM64: dts: meson-gxl: improve support for the P212 reference design

The Amlogic P212 reference design is used by other devices as well, such
as (for example) the Khadas VIM boards. Thus this patch adds and moves
all common entries from meson-gxl-s905x-p212.dts to a new, separate
meson-gxl-s905x-p212.dtsi (which can be re-used on boards such as the
Khadas VIM).
Support for all boards based on the P212 reference design includes:
- enabling IR support
- enabling the SAR ADC (SARADC_CH1 is connected to a resistor which
indicates the hardware revision, a similar design is found on the
Khadas VIM boards)
- all MMC controllers (which means that SDIO wifi, the SD card and the
eMMC are now supported)
- pwm_ef as dependency for the SDIO wifi module
- uart_A which is connected to the bluetooth module (the bluetooth
module itself is not enabled yet due to missing devicetree bindings
for the Broadcom serial bluetooth devices)
- uart_AO is moved to the .dtsi (as all known devices use it as their
boot-console)
Specific to the P212 board:
- this also enables the CVBS connector (which is not available on the
Khadas VIM boards for example)
