arm64: dts: ti: k3-j784s4-evm: Add phase tags marking

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, fss, ospi0, ospi1, main_sdhci0 and
main_sdhci1 are required for bootloader operation on TI K3 J784S4 EVM.
These IPs along with pinmuxes need to be marked for all bootloader phases,
hence add bootph-all to these nodes in kernel dts.
