OMAP2+: hwmod: Update the sysc_cache in case module context is lost

Do not skip the sysc programming in the hmwod framework based
on the cached value alone, since at times the module might have lost
context (due to the Powerdomain in which the module belongs
transitions to either Open Switch RET or OFF).

Identifying if a module has lost context requires atleast one
register read, and since a register read has more latency than
a write, it makes sense to do a blind write always.
