MediaTek Helio X10 MT6795 - Clock drivers

In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.

This (very big) series introduces system clock, multimedia clock drivers
(including resets) for this SoC.

Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.

This series depends on, and can be merged on top of:
[1]: https://patchwork.kernel.org/project/linux-mediatek/list/...
[2]: https://patchwork.kernel.org/project/linux-mediatek/list/...

Changes in v6:
 - Added helper function to cleanly unregister ref2usb_tx clocks
 - Added missing error handling and remove function to clk-mt6795-mm

Changes in v5:
 - Renamed clock/reset header filenames to add vendor prefix
 - Removed quotes for $id, $schema in commit [4/7]

Changes in v4:
 - Removed unnecessary examples for clock controllers in commit [4/7]
 - Fixed one instance of 88 columns line wrap in commit [4/7]

Changes in v3:
 - Fixed typo in commit [4/7]

Changes in v2:
 - Fixed yaml clock bindings as per Rob's review
 - Added ability to compile all MT6795 clock drivers as modules
 - Added commits to export some symbols, required to compile as module
