ARM: keystone: Drop the un-necessary dsb from keystone_cpu_smc()
This was added because of some legacy reasons from OMAP SOCs but after testing and verifying with the keystone hardware folks, the dsb in keystone_cpu_smc() is not necessary. So drop it. Reported-by: Dave Martin <dave.martin@linaro.org> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
