soc: mediatek: mtk-infracfg: Disable ACP on MT8192
MT8192 contains an experimental Accelerator Coherency Port
implementation, which does not work correctly but was unintentionally
enabled by default. For correct operation of the GPU, we must set a
chicken bit disabling ACP on MT8192.
Adapted from the following downstream change to the out-of-tree, legacy
Mali GPU driver:
https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/2781271/5
Note this change is required for both Panfrost and the legacy kernel
driver.
