ARM: OMAP2+: gpmc: handle additional timings
Configure busturnaround, cycle2cycledelay, waitmonitoringtime, clkactivationtime in gpmc_cs_set_timings(). This is done so that boards can configure these parameters of gpmc in Kernel instead of relying on bootloader. Also configure bool type timings like extradelay. This needed change to the existing users that were configuring clk activation time and extra delay by directly writing to registers. Thanks to Tony for making me aware of users of clk activation and being kind enough to test the modified one. Signed-off-by: Afzal Mohammed <afzal@ti.com>
