From: Peng Fan <peng.fan@nxp.com>

Previously there is an effort from Abel that take BLK-CTL as clock
provider, but it turns out that there is A/B lock issue and we are
not able resolve that.

Per discuss with Lucas and Jacky, we made an agreement that take BLK-CTL
as a power domain provider and use GPC's domain as parent, the consumer
node take BLK-CTL as power domain input.

This patchset has been tested on i.MX8MM EVK board, but one hack
is not included in the patchset is that the DISPMIX BLK-CTL MIPI_M/S_RESET
not implemented. Per Lucas, we will finally have a MIPI DPHY driver,
so fine to leave it.

Thanks for Lucas's suggestion, Frieder Schrempf for collecting
all the patches, Abel's previous BLK-CTL work, Jacky Bai on help
debug issues.
