Revert commit 
75b18aac6fa3 ("MIPS: unhide PATA_PLATFORM") now that
HAVE_PATA_PLATFORM is set selectively for all the relevant platforms.
Verified with `db1xxx_defconfig' and `sb1250_swarm_defconfig' by making
sure PATA_PLATFORM is still there in `.config' with this change applied,
and with `malta_defconfig' by making sure it's now gone.
