Chen-Yu Tsai 609cc5e1a8 clk: mediatek: Replace 'struct clk' with 'struct clk_hw' 
As part of the effort to improve the MediaTek clk drivers, the next step
is to switch from the old 'struct clk' clk prodivder APIs to the new
'struct clk_hw' ones.

Instead of adding new APIs to the MediaTek clk driver library mirroring
the existing ones, moving all drivers to the new APIs, and then removing
the old ones, just migrate everything at the same time. This involves
replacing 'struct clk' with 'struct clk_hw', and 'struct clk_onecell_data'
with 'struct clk_hw_onecell_data', and fixing up all usages.

For now, the clk_register() and co. usage is retained, with __clk_get_hw()
and (struct clk_hw *)->clk used to bridge the difference between the APIs.
These will be replaced in subsequent patches.

Fix up mtk_{alloc,free}_clk_data to use 'struct clk_hw' by hand. Fix up
all other affected call sites with the following coccinelle script.
