omap1: Add 7xx clocks and pin muxes for SPI
Commit 35c9049b27040d09461bc90928ad770be7ddf661 added drivers/spi/omap_spi_100k.c. This patch add the related clocks and pin muxing entries to make the driver work on omap7xx platforms. Signed-off-by: Cory Maccarrone <darkstar6262@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
