mailbox: Improve RISCV_SBI_MPXY_MBOX guidance

RISC-V SBI Message Proxy (MPXY) Mailbox support defaults to enabled, but
the help text states "If unsure say N".

Recommend enabling this driver, as it is a very critical RISC-V driver
providing mailbox channels to other drivers such as clock, system MSIs,
etc.

The ARCH_MICROCHIP symbol has been defined for some time on RISCV, as a
replacement for ARCH_MICROCHIP_POLARFIRE since there are now other
Microchip RISC-V products. Drop the POLARFIRE from
ARCH_MICROCHIP_POLARFIRE in the POLARFIRE_SOC_MAILBOX Kconfig entry
since the newly added pic64gx also uses the mailbox and it is one of the
few users of ARCH_MICROCHIP_POLARFIRE left in the tree.

mailbox: add MediaTek GPUEB IPI mailbox

The MT8196 SoC uses an embedded MCU to control frequencies and power of
the GPU. This controller is referred to as "GPUEB".

It communicates to the application processor, among other ways, through
a mailbox.

The mailbox exposes one interrupt, which appears to only be fired when a
response is received, rather than a transaction is completed. For us,
this means we unfortunately need to poll for txdone.

The mailbox also requires the EB clock to be on when touching any of the
mailbox registers.

Add a simple driver for it based on the common mailbox framework.

Merge tag 'riscv-for-linus-6.18-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull more RISC-V updates from Paul Walmsley:

- Support for the RISC-V-standardized RPMI interface.

RPMI is a platform management communication mechanism between OSes
running on application processors, and a remote platform management
processor. Similar to ARM SCMI, TI SCI, etc. This includes irqchip,
mailbox, and clk changes.

- Support for the RISC-V-standardized MPXY SBI extension.

MPXY is a RISC-V-specific standard implementing a shared memory
mailbox between S-mode operating systems (e.g., Linux) and M-mode
firmware (e.g., OpenSBI). It is part of this PR since one of its use
cases is to enable M-mode firmware to act as a single RPMI client for
all RPMI activity on a core (including S-mode RPMI activity).
Includes a mailbox driver.

- Some ACPI-related updates to enable the use of RPMI and MPXY.

- The addition of Linux-wide memcpy_{from,to}_le32() static inline
functions, for RPMI use.

- An ACPI Kconfig change to enable boot logos on any ACPI-using
architecture (including RISC-V)

- A RISC-V defconfig change to add GPIO keyboard and event device
support, for front panel shutdown or reboot buttons
