These patches are part of a larger effort to support the MT6735 SoC family in mainline
Linux. More patches (unsent or sent and pending review or revision) can be found here[1].

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/reset controllers, support for which is
not included in this series:
- mfgcfg (GPU)
- imgsys (camera)
- mmsys (display)
- vdecsys (video decoder)
- vencsys (video encoder)
- audsys (audio)

Changes since v2:
- Add "CLK_" prefix to infracfg and pericfg clock definitions to avoid possible
  clashes with reset bindings.
- Replace "_RST" suffix with "RST_" prefix to maintain consistency with clock bindings.
- Use macros to define clocks.
- Abandon mtk_clk_simple_probe/mtk_clk_simple_remove in favor of custom functions in apmixedsys
  and topckgen drivers for the time being. 
- Capitalize T in MediaTek in MODULE_DESCRIPTION.
Changes since v1:
- Rebase on some pending patches.
- Move common clock improvements to a separate series.
- Use mtk_clk_simple_probe/remove after making them support several clock types
  in said series.
- Combine all 4 drivers into one patch, and use one Kconfig symbol for all
  following a conversation seen on a different series[2].
- Correct APLL2 registers in apmixedsys driver (were offset backwards by 0x4).
- Make irtx clock name lower case to match the other clocks.
