clk: mediatek: Remove CLK_SET_PARENT from all MSDC core clocks

Various MSDC core clocks, used for multiple MSDC controller instances,
share the same parent(s): in order to add parents selection in the
mtk-sd driver to achieve an accurate clock rate for all modes, remove
the CLK_SET_RATE_PARENT flag from all MSDC clocks for all SoCs: this
will make sure that a clk_set_rate() call performed for a clock on
a secondary controller will not change the rate of a common parent,
which would result in an overclock or underclock of one of the
controllers.

clk: mediatek: Make mtk_clk_simple_remove() return void

__mtk_clk_simple_remove() and so also mtk_clk_simple_remove() return
zero unconditionally. Make them return no value instead and convert the
drivers making use of it to platform_driver's .remove_new().

This makes the semantics in the callers of mtk_clk_simple_remove() clearer
and prepares for the quest to make platform driver's remove function return
void. There is no semantic change.

clk: mediatek: Add MODULE_DEVICE_TABLE() where appropriate

Add a MODULE_DEVICE_TABLE() on all clocks that can be built as modules
to allow auto-load at boot.

clk: mediatek: mt8173: Migrate pericfg/topckgen to mtk_clk_simple_probe()

Function mtk_clk_simple_probe() gained the ability to register multiple
clock types: migrate MT8173's pericfg and topckgen to this common
probe function to reduce duplication and code size.

clk: mediatek: mt8173: Break down clock drivers and allow module build

Split the giant clock driver for MT8173 into smaller drivers and
make it possible to build the non boot critical clock controller
drivers as modules by adding remove functions and both module
description and license where needed.
While at it, also change a mtk_register_reset_controller() call
to mtk_register_reset_controller_with_dev() in mt8173-infracfg.

Some spare code style cleanups were also performed.
