Fix build failure for drivers/ata/pata_scc.c

Browse source 
The commit d4b2bab4f2 added deadline support
to prereset and reset methods to libbata the pata_scc driver wasn't
converted.  This patch is a naive attempt to bring this driver up to
scratch.

Build failures are:
drivers/ata/pata_scc.c: In function 'scc_pata_prereset':
drivers/ata/pata_scc.c:870: error: too few arguments to function 'ata_std_prereset'
drivers/ata/pata_scc.c: In function 'scc_error_handler':
drivers/ata/pata_scc.c:916: warning: passing argument 2 of 'ata_bmdma_drive_eh' from incompatible pointer type
drivers/ata/pata_scc.c:916: warning: passing argument 3 of 'ata_bmdma_drive_eh' from incompatible pointer type
drivers/ata/pata_scc.c: In function 'scc_pata_prereset':
drivers/ata/pata_scc.c:871: warning: control reaches end of non-void function

On a releated note scc_bus_post_reset() is (AFACT) identical to
ata_bus_post_reset(), would a patch to make ata_bus_post_reset() assesable
to drivers be accepted?
