This patchset mainly adds support for M4U of mt2712.
The M4U in mt2712 is MTK's generation2 M4U which use the
Short-descriptor like mt8173. The main difference is that there are 2
M4Us and 2 smi-commons in mt2712, while there is only 1 M4U and 1
smi-common in mt8173. The purpose is for balance the bandwidth.
The mt2712 M4U-SMI HW diagram is as below:
