Subject: [PATCH v4 2/3] 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_uart0, 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.
