Since the discussion is not settled yet for the EMAC, and that the release
in getting really close, let's revert the changes for now, and we'll
reintroduce them later.

This adds the reference in the device tree describing this relationship.

The new Allwinner H5 SoC is pin-compatible to the H3 SoC, but with the
Cortex-A7 cores replaced by Cortex-A53 cores and the MMC controller
updated. So we should really share almost the whole .dtsi.
In preparation for that move the peripheral parts of the existing
sun8i-h3.dtsi into a new sunxi-h3-h5.dtsi.
The actual sun8i-h3.dtsi then includes that and defines the H3 specific
parts on top of it.

According to the datasheets provided by Allwinner, both Allwinner H3 and
H5 use GIC-400 as their interrupt controller.

For better device tree reusing, correct the GIC compatible in H3 DTSI to
"arm,gic-400", thus this node can be reused in H5.

Since everybody copied my own mistake from the DT binding example,
let's address all the offenders in one swift go.

Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).

In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.

In the past, all the MMC pins had

	allwinner,pull = <SUN4I_PINCTRL_NO_PULL>;

which was actually a no-op. We were relying on U-boot to set the bias
pull up for us. These properties were removed as part of the fix up to
actually support no bias on the pins. During the transition some boards
experienced regular MMC time-outs during normal operation, while others
completely failed to initialize the SD card.

Given that MMC starts in open-drain mode and the pull-ups are required,
it's best to enable it for all the pin settings.

This was done to make UART1-3 on H3 consistent, and less complicated to
enable UART1-3 on the breakout header on the several H3 board (notably
Orange Pi's). This patch adds a bit of complexity for the existing Banana
Pi, which already had the RTS/CTS associated on UART1.

The RTS/CTS for UART2-3 could be defined in the same way, but since
there is no actual use case for them at the moment, they are left out.

These are the pinmux definitions for UART2-3 on H3. These UARTs can only
be muxed to these pins, so _a and @0 do not really make sense. I have
left out RTS/CTS, since these are rarely used. These can easily be
enabled using an additional pinmux set.
