Use the PRVERB() macro instead of 'if (bootverbose) printf()...

Add debuging for all failure cases in aha_cmd().

Always check DATAIN_REG_READY even if we're ready to exit the
read loop.

The last fix allows the AHA-1640 MCA SCSI adapter to operate
correctly and likely fixes problems on a few other oddball
adapters. (I suspect my Dell Drive Array in 1540 mode needs this.)
