pata-rb532-cf: get rid of the irq_to_gpio() call
The RB532 platform specific irq_to_gpio() implementation has been
removed with commit 832f5dacfa0b ("MIPS: Remove all the uses of
custom gpio.h"). Now the platform uses the generic stub which causes
the following error:
pata-rb532-cf pata-rb532-cf: no GPIO found for irq149
pata-rb532-cf: probe of pata-rb532-cf failed with error -2
Drop the irq_to_gpio() call and get the GPIO number from platform
data instead. After this change, the driver works again:
scsi host0: pata-rb532-cf
ata1: PATA max PIO4 irq 149
ata1.00: CFA: CF 1GB, 20080820, max MWDMA4
ata1.00: 1989792 sectors, multi 0: LBA
ata1.00: configured for PIO4
scsi 0:0:0:0: Direct-Access ATA CF 1GB 0820 PQ: 0\
ANSI: 5
sd 0:0:0:0: [sda] 1989792 512-byte logical blocks: (1.01 GB/971 MiB)
sd 0:0:0:0: [sda] Write Protect is off
sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't\
support DPO or FUA
sda: sda1 sda2
sd 0:0:0:0: [sda] Attached SCSI disk
Fixes: 832f5dacfa0b ("MIPS: Remove all the uses of custom gpio.h")
