Subject: [PATCH 0/3] clk: mediatek: mt8183: Simplify with mtk_clk_simple_*()

As part of clk driver support for MT8192, a pair of "simple"
probe/remove functions was introduced that provided boilerplate
driver functions for clk drivers that fit a simple model: they only
needed to register clock gates. Using them reduces the redundant
boilerplate code needed for each driver. Instead, only a data structure
pointing to the clock gate array and the number of clocks is needed.

This series converts all the MT8183 clock drivers that only contain
clock gates over to these wrapper functions. For instances where the
clk driver not only registers clock gates, the extra action is properly
sequenced with the wrapper functions instead of outright replacing
the probe functions. The converted drivers also get removal support.
This also reduces the overall size by nearly 600 bytes.

Patch 1 converts the MT8183 clk drivers that only do clock gate
registration.

Patch 2 converts the audio clk driver, which also populates sub-devices.

Patch 3 converts the mfgcfg (GPU wrapper) clk driver, which also needs
to enable runtime PM, as it is tied to a power domain.

Please have a look, and merge if possible.

Thanks
ChenYu
