[PATCH 3/3] dts: rockchip: rk3308: Avoid warning for serial probe on prereloc

[Massimo Pegorer]

Make device tree complete and consistent for pre relocation phase. Some
nodes are missing, causing warnings to be issued on serial port probing
during pre relocation phase (uclass_get_device_by_phandle_id fails when
called by pinctrl_select_state_full: none of these failures is fatal
nor causing issues). Add to *-u-boot.dtsi all required nodes with the
'bootph-some-ram' attribute.
