ARM: omap1: move CF chipselect setup to board file
There is only one board that uses the omap_cf driver, so moving the chipselect configuration there does not lead to code duplication but avoids the use of mach/tc.h in drivers. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Say Y here to support the CompactFlash controller on OMAP.
Note that this doesn't support "True IDE" mode.
