Not sure about this one yet. AFAICT this totally disables the HBA power 
control.

I'm wondering if this is a common problem.

It seems to me  that its likely that clock and power control are often 
external to the host controller chip. (not just on TMIO MMC).

I think it'd be a good idea if we came up with an infrastructre that 
allowed a set of clock / power control callbacks into the platform code.

Whats your use case for this? samee applies to the related cnf patch too.
