So this is a silicon block clock and falls into the category of things
we've been discussing...

If I understand correctly, the only "real" solution is to
implement the PM domains and have these enable the clocks.

An alternative may be to move this driver over to the AMBA bus,
because I think this device actually has primecell registers.
Then the bus will take care of the pclk for starters.
