Fix both these issues.

V1-V2:
- Fixed the check:
if (pl022-vendor-max_bpw = 32)
- Re-written complete range check logic.
Looks correct to me:

Mark: as Rabin says the v1 patch is probably fine, are you pushing this

That said I'm all for replacing it - but I'd need to figure out the
details on how to do that.
We do have code for ux500 power domains. If it will will be
enough to handle this I can try to hack it up and submit it.

is really lost...
And I do like the change, if for nothing else so for the fact that it
eventually pushes to power domains what belongs there, so:

But to the defence: power domain code was not in the kernel

How can there be a power regression here

do any deeper review.)
