[U-Boot] [PATCH v2 3/4] novena: Move the DCD settings to spl code

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

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.
