[PATCH V4 04/49] imx: spl: Allow iMX7/8/8M to overwrite spl_board_boot_device

[Peng Fan (OSS)]

From: Ye Li <ye.li at nxp.com>

Move the default mapping of spl_boot_device to weak function of
spl_board_boot_device. So that every board of iMX7/8/8M can overwrite
this function to implement specific mapping.
