Add support for the GMAC found in the Allwinner R40/V40 SoC.
The R40 GMAC interface is not controlled by the syscon register but
has a separate configuration register in the CCU.
The clock gate and reset bits are in a different register compared
to the other SoCs supported by this driver.
The driver uses the -gmac suffix for the R40 because the R40 also
has a different 100 MBit MAC (EMAC).

arm64: dts: allwinner: h5: Add cpu0 label for first cpu
Since the H3 and H5 are very similar (aside from the actual ARM cores),
they share most the SoC .dtsi and thus have to be updated together.
One tiny change is the removal of the "arm/" prefix from the include
path in the sun50i-h5.dtsi, which is needed because we don't share the
same sophisticated DT directory layout of Linux.
Also we need to fix up the board .dts files already, since the .dtsi
removes some pins, so the .dts can't reference them anymore. This is to
maintain bisectability.

In xfer function, both bus_i2c_read and bus_i2c_write will

Generally two operations comprise the register data reading:
1. Write the register address to i2c device.
START | chip_addr | W | ACK | register_addr | ACK |
2. Read the Data from i2c device.
START | chip_addr | R | ACK | DATA | NACK | STOP
The STOP command should happen at the end of the transfer, otherwise
we will always get data from register address 0

The SDRAM must first be rewritten by zeroes if ECC is used to initialize
the ECC metadata. Make the CPU overwrite the DRAM with zeroes in such a
case. This scrubbing implementation turns the caches on temporarily, then
overwrites the whole RAM with zeroes, flushes the caches and turns them
off again. This provides satisfactory performance.
