The infra_ao reset is needed for MT8192 and MT8195.
- Add mtk_clk_rst_desc for MT8192 and MT8195
- Add register reset controller function for MT8192 infra_ao.
- Move definition of infra reset from cl-mt8183.c to reset.h
because it's the same definition with MT8192 and MT8195.
- Add new definition of infra reset_4 for MT8192 and MT8195.
- Add infra_ao_idx_map for MT8192 and MT8195.

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.

When the PLL type clk was implemented in the MediaTek clk driver
library, the data structure definitions and function declaration
were put in the common header file.
Since it is its own type of clk, and not all platform clk drivers
utilize it, having the definitions in the common header results
in wasted cycles during compilation.
Split out the related definitions and declarations into its own
header file, and include that only in the platform clk drivers that
need it.
