[PATCH v5 00/14] Add BLK_CTL support for i.MX8MP

The BLK_CTL according to HW design is basically the wrapper of the entire
function specific group of IPs and holds GPRs that usually cannot be placed
into one specific IP from that group. Some of these GPRs are used to control
some clocks, other some resets, others some very specific function that does
not fit into clocks or resets. Since the clocks are registered using the i.MX
clock subsystem API, the driver is placed into the clock subsystem, but it
also registers the resets. For the other functionalities that other GPRs might
have, the syscon is used.

Changes since v4:
* added back the bus_blk_clk in the imx8mp blk_ctl driver (media_blk_ctl)
* added the R-b tag from Rob to the documentation patch
