Conke Hu 55a61604cd ahci.c: walkaround for SB600 SATA internal error issue 
There is a HW issue in ATI SB600 SATA that PxSERR.E should not be
set on some conditions, for example, when there is no media in SATA
CD/DVD drive or media is not ready, AHCI controller fails to execute
ATAPI commands and reports PORT_IRQ_TF_ERR, but ATI SB600 SATA
controller sets PxSERR.E at the
same time, which is not necessary.
    This patch is just to ignore the INTERNAL ERROR in such case.
Without this patch, ahci error handler will report many errors as
below:
    ----------- cut from dmesg -----------
ata9: soft resetting port
