OMAP3+: PM: VC: handle mutant channel config for OMAP4 MPU channel
On OMAP3+, all VC channels have the the same bitfield ordering for all VC channels, except the OMAP4 MPU channel. This appears to be a freak accident as all other VC channel (including OMAP5) have the standard configuration. Handle the mutant case by adding a per-channel flag to signal the deformity and handle it during VC init. Special thanks to Nishanth Menon <nm@ti.com> for finding this problem and for proposing the initial solution. Cc: Nishanth Menon <nm@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
