1. Add DDR script for mx6qpsabreauto board. 2. On CPU3 board, enet RGMII tx clock is from internal PLL. Set the GPR5[9] and init the enet pll output to 125Mhz. 3. On CPU3 board, SW1ABC=VDDSOC_IN, SW2=VDDARM_IN.

Note: In this patch, we still add a new config mx6qpsabreauto_config, since SPL is not supported now, and IMX_CONFIG is needed at build time, so add this config. Future, when SPL is converted, this config can be removed.

Changes v4: Add Fabio's Reviewed-by
Changes v3: 1. runtime setting DTB 2. In this patch, we still add a new config mx6qpsabreauto_config, since SPL is not supported now, and IMX_CONFIG is needed at build time, so add this config. All the patches in this patch set have been reworked with CONFIG_MX6QP removed to align with runtime check, but this IMX_CONFIG is needed at build time. Future, when SPL is converted, this config can be removed.
Changes v2: 1. Remove unused macro in current upstream uboot. 2. setup_fec, remove non 6qp code. Add comments for gpr setting. 3. mx6qp.cfg is still same with v1. The settings is from IC and passed memory ddr stress test. Since we current have no plan to add SPL, so leave settings unchanged.
