platform/x86: hp_accel: Use SIMPLE_DEV_PM_OPS() for PM ops 

After the commit 34570a898e ("platform/x86: hp_accel: Remove
_INI method call") there is no need to have separate methods for
resume and restore, hence we may fold them together and use
SIMPLE_DEV_PM_OPS() for PM ops.

While at it, switch to use __maybe_unused attribute.
