bootph-all as phase tag was added to dt-schema
(dtschema/schemas/bootph.yaml) to cover U-Boot challenges with DT.
That's why add it also to Linux to be aligned with bootloader requirement.
wkup_i2c0, mcu_uart0, main_uart8, main_sdhci0 and main_sdhci1 are required
for bootloader operation on TI K3 AM69-SK EVM. These IPs along with
pinmuxes need to be marked for all bootloader phases, hence add bootph-all
to these nodes in kernel dts.
