sata_mv: increase PIO IORDY timeout
The old value (0xbc) in cycles of the IORDY timeout is suitable for devices with core clock of 166 MHz, but some SoC controllers have faster core clocks. The new value will make the IORDY timeout large enough also for all SoC devices. Signed-off-by: Saeed Bishara <saeed@marvell.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
