Sorry for the lag.
Tested on 7425b2, there is a small mistake in the interrupt number for
the AHCI controller in the 7425.dtsi file (40 -> 41, see below), after
fixing that, I get both drives (external and internal ports) to be
identified successfully:
# dmesg | grep scsi
<6>[ 0.964097] scsi host0: brcm-ahci
<6>[ 0.967982] scsi host1: brcm-ahci
<5>[ 1.122386] scsi 0:0:0:0: Direct-Access ATA WDC
WD2500AAKX-7 1H19 PQ: 0 ANSI: 5
<5>[ 1.124512] sd 0:0:0:0: Attached scsi generic sg0 type 0
<5>[ 1.411546] scsi 1:0:0:0: Direct-Access ATA WDC
WD2500AAKX-7 1H19 PQ: 0 ANSI: 5
<5>[ 1.428870] sd 1:0:0:0: Attached scsi generic sg1 type 0

And performance looks good:
# hdparm -tT /dev/sda
/dev/sda:
[ 48.557068] random: nonblocking pool is initialized
Timing buffer-cache reads: 524 MB in 0.50 seconds = 1052111 kB/s
Timing buffered disk reads: 358 MB in 3.00 seconds = 122132 kB/s
# hdparm -tT /dev/sdb
/dev/sdb:
Timing buffer-cache reads: 528 MB in 0.50 seconds = 1060559 kB/s
Timing buffered disk reads: 374 MB in 3.00 seconds = 127496 kB/s

For interrupt numbers, computing them from the HIF_CPU_INTR1 register
works like this this:
HW IRQ# = N * 32 + M
where N ranges from 0->2 and M is the bit within the 32-bits word.
Thanks!
