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_uart0, 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.
