Drop the check for "up" being valid on suspend/resume callbacks.
It should be valid always. Get rid of the "pdata" check also as
serial_omap_get_context_loss_count() checks for it.

Boot tested on omap4 panda and PM tested(hitting off in Idle
and suspend) on 3630 based Beagle board.

Not a functionality change, just
Introduce a blank line before "signed off by" line.
