Reading the GPIOs for getting the boot mode does not show the correct result
for USB boot mode in case the recovery switch, eg. BM2 for switching from NAND
to USB boot mode, is hold down while plugging in USB and released before U-Boot
is loaded by mxsldr.
This state is stored in the HW_OCOTP_ROM0 register. HW_OCOTP_ROM0[27:24] maps to
BM3-BM0, HW_OCOTP_ROM0[28] maps to voltage selector.
For using mxs_wait_mask_clr() add imx-common/misc.o to the SPL build.
