Merge series from Li Zetao <lizetao1@huawei.com>:
Commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared
and enabled clocks") provides a new helper function for prepared and
enabled clocks when a driver keeps a clock prepared (or enabled) during
the whole lifetime of the driver. So where drivers get clocks and enable
them immediately, it can be combined into a single function
devm_clk_get_*(). Moreover, the unprepare and disable function
has been registered to devm_clk_state, and before devm_clk_state is
released, the clocks will be unprepareed and disable, so it is unnecessary
to unprepare and disable clocks explicitly when remove drivers or in the
error handling path.

Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared
and enabled clocks"), devm_clk_get() and clk_prepare_enable() can now be
replaced by devm_clk_get_enabled() when driver enables (and possibly
prepares) the clocks for the whole lifetime of the device. Moreover, it is
no longer necessary to unprepare and disable the clocks explicitly.
Also, devm_clk_get_optional() and clk_prepare_enable() can now be
replaced by devm_clk_get_optional_enabled().Moreover, the two functions
mtk_snand_enable_clk() and mtk_snand_disable_clk() no longer are used,
drop them for clean code.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
