I am not sure if we even have any modules on OMAP4 which *do not*
support module level context loss status and for which we need to fall
back on pwrdm level status. So maybe we could even get rid of the check
for a valid context_offset altogether and expect it to be populated for
all modules as we do with the clkctrl offset.
