(2.6.20) pata_mpiix: probing cleanup (resend)
MPIIX has only single channel IDE which can be configured for either primary or
secondary legacy I/O ports and IRQ. So, get rid of the unneeded second probe
entry in mpiix_init_one() and of the invalid (but unused anyway) enable bits in
mpiix_pre_reset().
Warning: this cleanup has only been compile-tested...
