[V2,0/9] arm64: imx8mn: Enable additional power domains and peripherals

Message

The blk-ctrl and the GPCv2 in the i.MX8MN is similar but slightly different to that
of the i.MX8MM.  This series is based on work from Lucas Stach for i.MX8MM, but
adapted for i.MX8MN.  With the additional power domains and blk-ctrl enabled,
additional peripherals like gpu and USB can be enabled.

V2:  Add mising patches for expanding GPCv2 which are necessary
       to make the blk-ctl operate.
     Fix clk names
     Fix missing references to structures in blk-ctl driver to link
       them to the device tree.

I know Rob had some feedback on the DT bindings updates.  I can
address them in V3, I was hoping to get some feedback from this series
from others who may be interested.

I don't know if it's too late to get this into 5.16 or not, but I'll
submit a V3 this weekend.
