Subject: [PATCH] sh: cayman: IDE support fix

Remove incorrect CONFIG_IDE ifdef (CONFIG_IDE config option
is for internal drivers/ide/ use) and make IDE hardware
interface always initialized (not only when IDE subsystem
is built-in).

This patch allows Cayman board to work with modular IDE
subsystem support and removes the requirement of having
the whole core IDE subsystem built-in when using libata
PATA support.
