ide: remove stale ide.h "configuration options"

Browse Source 
Remove stale ide.h "configuration options":

* INITIAL_MULT_COUNT - always defined to 0

* SUPPORT_SLOW_DATA_PORTS - unused

* OK_TO_RESET_CONTROLLER - always defined to 1

* DISABLE_IRQ_NOSYNC - always defined to 0

Leave SUPPORT_VLB_SYNC (defined to 0 for CRIS and FRV, otherwise to 1)
for now but disallow overriding it by <asm/ide.h>.

There should be no functionality changes caused by this patch.
