Add reset controller driver for the T-HEAD TH1520 SoC that manages
hardware reset lines for various subsystems. The driver currently
implements support for GPU reset control, with infrastructure in place
to extend support for NPU and Watchdog Timer resets in future updates.

riscv: dts: thead: th1520: Add GPU clkgen reset to AON node
2ea30e7 
mainline inclusion
from Linux 7.0-rc3
commit cf5e81d
category: feature
bugzilla: RVCK-Project#236

--------------------------------

Add the "gpu-clkgen" reset property to the AON device tree node. This
allows the AON power domain driver to detect the capability to power
sequence the GPU and spawn the necessary pwrseq-thead-gpu auxiliary
driver for managing the GPU's complex power sequence.

This commit also adds the prerequisite
dt-bindings/reset/thead,th1520-reset.h include to make the
TH1520_RESET_ID_GPU_CLKGEN available. This include was previously
dropped during a conflict resolution [1].

mailbox: Introduce support for T-head TH1520 Mailbox driver
360c5c0 
mainline inclusion
from Linux 7.0-rc5
commit 5d4d263
category: feature
bugzilla: RVCK-Project#240

--------------------------------

This driver was tested using the drm/imagination GPU driver. It was able
to successfully power on the GPU, by passing a command through mailbox
from E910 core to E902 that's responsible for powering up the GPU. The
GPU driver was able to read the BVNC version from control registers,
which confirms it was successfully powered on.

[   33.957467] powervr ffef400000.gpu: [drm] loaded firmware
powervr/rogue_36.52.104.182_v1.fw
[   33.966008] powervr ffef400000.gpu: [drm] FW version v1.0 (build
6621747 OS)
[   38.978542] powervr ffef400000.gpu: [drm] *ERROR* Firmware failed to
boot

Though the driver still fails to boot the firmware, the mailbox driver
works when used with the not-yet-upstreamed firmware AON driver. There
is ongoing work to get the BXM-4-64 supported with the drm/imagination
driver [1], though it's not completed yet.

This work is based on the driver from the vendor kernel [2].
