From: Yassine Oudjana <[e-mail]>

This series adds support for the main clock and reset controllers on the
Mediatek MT6735 SoC:
- apmixedsys (global PLLs)
- topckgen (global divisors and muxes)
- infracfg (gates and resets for internal components)
- pericfg (gates and resets for peripherals)

MT6735 has other more specialized clock controllers, support for which is
not included in this series:
- imgsys (camera)
- mmsys (display)
- vdecsys (video decoder)
- audsys (audio)

Some symbols in common objects are exported to get the drivers to compile
as modules, and mtk_unregister_reset_controller() is implemented to allow
for unregistering reset controllers in the infracfg and pericfg drivers
when unloading them.
