to allow auto-load at boot.

Take a pointer to a struct device in mtk_clk_register_cpumuxes() and
propagate the same to mtk_clk_register_cpumux() => clk_hw_register().
Even though runtime pm is unlikely to be used with CPU muxes, this
helps with code consistency and possibly opens to commonization of
some mtk_clk_register_(x) functions.

Commit e4c23e19aa ("clk: mediatek: Register clock gate with device")
introduces a helper function for the sole purpose of propagating a
struct device pointer to the clk API when registering the mtk-gate
clocks to take advantage of Runtime PM when/where needed and where
a power domain is defined in devicetree.
Function mtk_clk_register_gates() then becomes a wrapper around the
new mtk_clk_register_gates_with_dev() function that will simply pass
NULL as struct device: this is essential when registering drivers
with CLK_OF_DECLARE instead of as a platform device, as there will
be no struct device to pass... but we can as well simply have only
one function that always takes such pointer as a param and pass NULL
when unavoidable.
This commit removes the mtk_clk_register_gates() wrapper and renames
mtk_clk_register_gates_with_dev() to the former and all of the calls
to either of the two functions were fixed in all drivers in order to
reflect this change; also, to improve consistency with other kernel
functions, the pointer to struct device was moved as the first param.
Since a lot of MediaTek clock drivers are actually registering as a
platform device, but were still registering the mtk-gate clocks
without passing any struct device to the clock framework, they've
been changed to pass a valid one now, as to make all those platforms
able to use runtime power management where available.
While at it, some much needed indentation changes were also done.

Add the clock drivers for the entire clock tree of MediaTek Helio X10
MT6795, including system clocks (apmixedsys, infracfg, pericfg, topckgen)
and multimedia clocks (mmsys, mfg, vdecsys, vencsys).
