[U-Boot] [PATCH 2/6] spl: Add function to get u-boot raw sector

[Peng Fan <peng.fan@nxp.com>]

Add a weak function spl_mmc_get_uboot_raw_sector to get u-boot raw
sector. At default it returns CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR.
Users can overwrite it to return customized offset.

This is to support i.MX8 specific image type container image type.
