Alyssa Rosenzweig dcfd519256 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.

Chun-Kuang Hu 1570db1da9 soc: mediatek: cmdq: Remove cmdq_pkt_flush() 
rx_callback is a standard mailbox callback mechanism and could
cover the function of proprietary cmdq_task_cb, so it is better
to use the standard one instead of the proprietary one. But
register rx_callback should before mbox_request_channel(),
so remove cmdq_pkt_flush() and let client driver implement
its own synchronous flush.

Miles Chen c2c59456e1 iommu/mediatek: Check 4GB mode by reading infracfg 
In previous discussion [1] and [2], we found that it is risky to
use max_pfn or totalram_pages to tell if 4GB mode is enabled.

Check 4GB mode by reading infracfg register, remove the usage
of the un-exported symbol max_pfn.

This is a step towards building mtk_iommu as a kernel module.
