This is the last man standing in clk-mt8192.c that won't allow us to
use the module_platform_driver() macro, and for *no* good reason.
Move it to clk-mt8192-apmixedsys.c and while at it, also add a
.remove() callback for it.

Also, since the need for "clk-mt8192-simple" and "clk-mt8192" was
just due to them being in the same file and probing different clocks,
and since now there's just one platform_driver struct per file, it
seemed natural to rename the `-simple` variant to just "clk-mt8192".

All the above combined, I think this patch is doing a bit too much, but
splitting it probably doesn't make much sense either :/
