Most R-Car Gen3 and Gen4 systems require extalr_clk very early
in the boot process. Currently the extalr_clk { bootph-all } DT
property to indicate this clock should be available early is set
in each SoC U-Boot DT extras file. Deduplicate this assignment to
new common r8a779x-rcar64-u-boot.dtsi file.
Note that R-Car Gen3 R8A77990 E3 and R8A77995 D3 and RZ R8A774C0
do not require extalr_clk early, therefore these SoCs still include
plain r8a779x-u-boot.dtsi in their U-Boot DT extras .

The correct spelling is R-Car, including the dash, update the usage.
Comment change only, no functional change.

The compatible values used for device nodes representing Renesas Reduced
Pin Count Interfaces were based on preliminary versions of the Device
Tree Bindings.
Correct them in both DTSi files and drivers, to match the final DT
Bindings.
Note that there are no DT bindings for RPC-IF on RZ/A1 yet, hence the
most logical SoC-specific value is used, without specifying a
family-specific value.

According to the Generic Names Recommendation in the Devicetree
Specification Release v0.3, and the DT Bindings for the Renesas Reduced
Pin Count Interface, the node name for a Renesas RPC-IF device should be
"spi". Especially on R-Car Gen3 and RZ/G2, the node name matters, as
the node is enabled by passing a DT fragment from TF-A to U-Boot, and
from U-Boot to subsequent software.
Fix this by renaming the device nodes from "rpc" to "spi".

Remove the leading "0x" from rpc node to fix the below dtc warning:
Warning (simple_bus_reg): Node /soc/rpc@0xee200000 simple-bus unit
address format error, expected "ee200000"
