c71321c7c6 dts: rockchip: rk3308: Avoid warning for serial probe on prereloc
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.

0cd87aac5c clk: rockchip: rk3308: Support reading UART rate and clock registers
Add support to read RK3308 registers used to configure UART clocks, and
thus to get UART rate and baudrate. This fixes clock_get_rate returning
error on serial device probing. Moreover, there is no need anymore to
use 'clock-frequency' property for UART nodes in *-u-boot.dtsi files
for all cases where UART is not inited by U-Boot proper or by SPL o by
TPL code but by a preliminary external boot phase (for Rock PI S, UART
is inited by external TPL).

1d7e1d09ca rockchip: rk3308: add support for sdmmc boot
Some ROCK Pi S SKU/models are not equipped with SD-NAND (eMMC),
therefore SPL needs access to sdmmc: add it to rk3308-u-boot.dtsi
with bootph-all property.

While this change is correct for v2023.04 it is not correct for next
(where this is right now) nor post-v2023.04.

This reverts commit 8653e5d3b7.

8653e5d3b7 rockchip: Fix early use of bootph props
Running U-Boot on a ROCK 3 Model A result in the following:

  No serial driver found
  resetting ...
  no sysreset
  ### ERROR ### Please RESET the board ###

Replace bootph- props with u-boot,dm- props to fix this.
