ahci_exec_fis: wait for the correct amount of time when AT_WAIT is set

Retry clearing WDCTL_RST a few times before giving up. Makes SATA work in
Solidrun Honeycomb LX2K.

AHCI 1.3.1 specification says that it is good practice for system software
to 'zero-out' the memory allocated and referenced by PxCLB and PxFB.

ahci_intr: use ffs in the port bitmask instead of looping over all 32 bits

AHCI 1.3.1 section 5.5.3 "Processing Completed Commands" says that we
should clear PxIS before IS.IPS.

Add G3 and DevSleep definitions. This changes the mask used by
SControl_IPM_NONE from 0x3 to 0x7.

Make sure to ack IS after PxIS when polling and when using multiple MSI-X
messages.

Remove the AHCI_QUIRK_SKIP_RESET quirk now that the underlying issue is
fixed.
