The idea was that this can be selected by CONFIG_PATA_OF_PLATFORM
in any configuration that has CONFIG_OF enabled. Since PPC
has CONFIG_OF enabled unconditionally, there is no need to
make this option visible separately.

Same for compile-testing: since CONFIG_OF can be enabled on
any architecture, PATA_OF_PLATFORM is already covered by
allmodconfig builds anywhere. The separate HAVE_PATA_PLATFORM
is only needed for machines that want the non-OF pata-platform
module (sh, m68k-mac, mips-sibyte arm-s3c-simtec).
