ahci: kill @force_restart and refine CLO for ahci_kick_engine()
This patch refines ahci_kick_engine() after discussion with Tejun about
FBS(FIS-based switching) support preparation:
a. Kill @force_restart and always kick the engine. The only case where
@force_restart is zero is when it's called from ahci_p5wdh_hardreset()
Actually at that point, BSY is pretty much guaranteed to be set.
b. If PMP is attached, ignore busy and always do CLO. (AHCI-1.3 9.2)
