[PATCH v2 00/13] Add generic MFD i.MX mix and audiomix support

[Abel Vesa]

The i.MX8MP has some new IPs called mixes. They are formed usually by some
GPRs that can be split into different functionalities. The first example
here is the audiomix which has dedicated registers that can be registered
as a clock controller and some other registers that can be registered as
a reset controller, plus some dedicated ones that will be registered as
syscon and used by each dedicated audio IP.

More mixes to be following the same structure are to come, like hdmimix,
dispmix and mediamix. They will all be populated and registered by the MFD
imx-mix generic driver.

Changes since RFC:
 * changed the gate2 to work as shared with single bit,
   therefor avoiding to add the new clk-gate-shared clock type.
 * implemented all Stephen's comments
 * implemented all Peng's comments
 * documented the DT bindings
