8c103c33fb dm: dts: Convert driver model tags to use new schema
Now that Linux has accepted these tags, move the device tree files in
U-Boot over to use them.

3d5f45c95c ARM: dts: rmobile: Disable RPC HF by default
The RPC HF might be locked by ATF, and any access to its register
space would result in complete hang. Disable the RPC HF by default.
The ATF should be patched to set RPC node status = "okay" in the DT
fragment it passes to U-Boot in case the RPC HF access is unlocked,
and that way U-Boot could access the RPC HF safely.

778fbe2668 ARM: dts: rmobile: Add sysinfo extras on R-Car Gen3
Add sysinfo node and phandle to the board ID EEPROM on all boards
where this functionality is described in DT, which is Salvator-X(S),
ULCB and Ebisu. The u-boot,dm-pre-reloc is necessary here, since the
sysinfo must be available early during boot. The V3M and V3H boards
currently do not describe this board ID EEPROM in upstream DT, but
that could be easily added later, once the DTs contain the necessary
nodes.

ULCB and Ebisu needs the full EEPROM node in the u-boot extras DT,
since the EEPROM node is still missing in the upstream DTs. Ebisu
also needs extra compatible string override for the i2c_dvfs.

16dcfbcd2b ARM: rmobile: Enable RPC on Salvator-X, ULCB, Ebisu
Enable the RPC Hyperflash driver on R8A7795,R8A7796,R8A77965
Salvator-X,ULCB and R8A77990 Ebisu. Note that to make the HF
accessible, mainline ATF is mandatory and must be built with
RCAR_RPC_HYPERFLASH_LOCKED=0 . Note that this is intended for
development and testing convenience only and must be disabled
in deployment for platform security reasons.

03578d940d ARM: dts: rmobile: Enable eMMC DDR52 modes on Gen3 Salvator-X(S),ULCB,Ebisu
Enable DDR52 modes, since the SD core supports correct switching now.
For completeness, list HS200 modes, however those were already enabled.
