So far this adds support for one Netgear model only, but it's designed
and ready to add many more device. We could hopefully import database
from OpenWrt.
Support for SSB is currently disabled, because SSB doesn't implement IRQ
domain yet.

So far this is mostly just a proof of concept, database consists of a
single device. Creating a nice iterateable array wasn't an option
because devices have different amount of LEDs. And we don't want to
waste memory just because of support for a device with dozens on LEDs.

The BCM4706 has a problem with the CPU wait instruction. When r4k_wait
or r4k_wait_irqoff is used will just hang and not return from a
msleep(). Removing the cpu_wait functionality is a workaround for this
problem. The BCM4716 does not have this problem.
The BCM4706 SoC uses a MIPS 74K V4.9 CPU.

Add MSI chip and MSIX chip definitions.
For MSI, we map the link interrupt to a MSI link IRQ which will
do a second level of dispatch based on the MSI status register.
The MSI chip definitions use the MSI enable register to enable
and disable the MSI irqs.
For MSI-X, we split the 32 available MSI-X vectors across the
four PCIe links (8 each). These PIC interrupts generate an IRQ
per link which uses a second level dispatch as well.
The MSI-X chip definition uses the standard functions to enable
and disable interrupts.

The io resource starting point on Malta was modified by c5de50dada (MIPS:
Malta: Change start address to avoid conflicts.) to avoid conflicts with
ACPI and SMB devices. In fact, that was not needed (and now causing
southbridge ACPI missing) since 166c637075 (PCI: add pci_create_root_bus()
that accepts resource list) and 7c090e5bfa (mips/PCI: convert to
pci_scan_root_bus() for correct root bus resources) had already done the
correct fix.
This patch actually reverts the change made by c5de50dada. And with this
fix, log says:

These things may not be used but as part of platform resources are better
off to be included.

Input GPIO changes can generate interrupts, but we need kind of ACK for
them by changing IRQ polarity. This is required to stop hardware from
keep generating interrupts and generate another one on the next GPIO
state change.
This code allows using GPIOs with standard interrupts and add for

The defaults are not always applicable and it makes it hard for the bootloader
to override them. By removing it we give the bootloader full control over what
command line parameters to pass.
Without this change we will need to modify the built-in dtb to add bootloader
cmd line parameters or do some work to append them after we unflatten the device
tree.
Sead3 is a development board, that's why we want to be able to change boot
parameters on the fly from the bootloader.

This patch switches Malta from using the MIPS implementation of early
printk with Malta's prom_putchar to using the generic 8250_early
implementation. This offers a couple of advantages:
- We duplicate less generic code.
- The UART can be initialised rather than being reliant upon
inheriting a valid setup from the bootloader.
The Malta console_config function is extended to initialise the early
console if no earlycon= kernel parameter is provided, inheriting the
modetty0 bootloader environment if present and falling back to a
default 38400n8r setup if not. This matches the behaviour used for the
regular console= parameter.

This patch causes the kernel to mux the SERIRQ interrupt to the SERIRQ
pin of the PIIX4 and to enable that interrupt. The kernel depends upon
the interrupt when using the SuperIO UARTs (ttyS0 & ttyS1) but
previously would not configure it, instead relying upon the bootloader
having done so. If that is not the case then the typical result is that
the system appears to hang once it reaches userland as no output is
displayed on the UART.
