rockchip: rk3588: Update bootph props

After the commit aca95282c1b7 ("Makefile: Use the fdtgrep -u flag")
bootph props is propagating to parent nodes.

Update bootph props to ensure eMMC, SD-card and SPI flash is available
in SPL and U-Boot proper pre-reloc phase also remove unneeded bootph
props that automatically is propagated to parent nodes.

Also adjust pinctrl nodes to only be included in boot phases where they
are needed and add any missing pinctrl node needed in SPL.
