Revert "imx: Introduce CONFIG_SPL_FORCE_MMC_BOOT to force MMC boot on falcon mode"

The CONFIG_SPL_FORCE_MMC_BOOT config flag is not needed as its behavior
is the correct one in all cases;  using spl_boot_device() instead of the
boot_device parameter will lead to inconsistency issues, for example,
when a board_boot_order() is defined.  In fact, this is the reason the
parameter was introduced in the first place, in commit 2b1cdafa9fdd
("common: Pass the boot device into spl_boot_mode()").

This reverts commit 772b55723bcbe8ebe84f579d9cdc831d8e18579d.
