PM:Some more cleanups in update_ec_eq procedure for core unit xstop case
- Enabled EX check. even if it's EQ is functional
- one more check of clock power off which is
required for mpipl case.
- had one bug during l2/l3 stop clock which fixes status bit update.
Actually clock was stopped but the status bit was not set
in EQ_CLOCK_STAT register.
