Add support for the RTL9302 SoC and the RTL9302C_2xRTL8224_2XGE
reference board.
The RTL930x family of SoCs are Realtek switches with an embedded MIPS
core (800MHz 34Kc). Most of the peripherals are similar to the RTL838x
SoC and can make use of many existing drivers.
Add in full DSA switch support is still a work in progress.

EyeQ6H (or “High”) is an other SoC from Mobileye still based on the
MIPS I6500 architecture as the EyeQ5. The 2 clusters of this SoC
contains 4 cores which are capable of running 4 threads. Besides this,
it features multiple controllers such as the classic UART, high speed
I2C, SPI, as well as CAN-FD, PCIe Gen4, Octal/Quad SPI Flash
interface, Gigabit Ethernet, MIPI CSI-2, MIPI DSI, and eMMC 5.1. It
also includes a Hardware Security Module, Functional Safety Hardware,
and video encoders and more.
This commit provides the infrastructure to build a kernel running on
EyeQ6H SoC. For now the support is limited and only one CPU core is
running.

Commit 08384e80a7 ("MIPS: DTS: CI20: Fix ACT8600 regulator node
names") caused the VDDCORE power supply (regulated by the ACT8600's
DCDC1 output) to drop from a voltage of 1.2V configured by the
bootloader, to the 1.1V set in the Device Tree.
According to the documentation, the VDDCORE supply should be between
0.99V and 1.21V; both values are therefore within the supported range.
However, VDDCORE being 1.1V results in the CI20 being very unstable,
with corrupted memory, failures to boot, or reboots at random. The
reason might be succint drops of the voltage below the minimum required.
Raising the minimum voltage to 1.125 volts seems to be enough to address
this issue, while still keeping a relatively low core voltage which
helps for power consumption and thermals.

Wire the WiFi/Bluetooth chip properly in the Device Tree.
- Provide it with the correct regulators and clocks;
- Change the MMC I/O bus to 1.8V which seems to be enough;
- Change the MMC I/O bus frequency to 25 MHz as 50 MHz causes errors;
- Fix the Bluetooth powerdown GPIO being inverted and add reset GPIO;
- Convert host-wakeup-gpios to IRQ.
With these changes, the WiFi works properly with the latest firmware
provided by linux-firmware. The Bluetooth does not work very well here,
as I cannot get my wireless keyboard to pair; but it does detect it, and
it does see the key presses when I type the pairing code.

The Device Tree was using invalid node names for the ACT8600 regulators.
To be fair, it is not the original committer's fault, as the
documentation did gives invalid names as well.
In theory, the fix should have been to modify the driver to accept the
alternative names. However, even though the act8865 driver spits
warnings, the kernel seemed to work fine with what is currently
supported upstream. For that reason, I think it is okay to just update
the DTS.
I removed the "regulator-name" too, since they really didn't bring any
information. The node names are enough.
