mx6sabresd: Move the DCD settings to spl code
mx6sabresd_spl.cfg configures CCM registers, GPR registers and CCM_CCOSR. Move the configuration to the spl code. CCM_CCOSR setting is no longer required to get audio functionality in the kernel, so remove such setting. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
