Reset controller updates for v5.8

Browse Source 
This tag adds support for i.MX8MP and i.MX8MN SoCs to the i.MX7 reset
 controller driver, extends the Hi6220 reset driver to support the AO
 reset controller used to bring the Mali450 GPU out of reset, and adds
 a define for the internal DAC reset line on Amlogic GXL SoCs.
