hikey: Add development TBB support
This patch adds experimental support for TRUSTED_BOARD_BOOT to the
Hikey. This is adapted from the RPi3 and QEMU implementations.
Since the Hikey starts from BL2 the TRUSTED_BOARD_BOOT ROT begins there
too. When TRUSTED_BOARD_BOOT is defined, the BL1 build is skipped.
See the following example:
make \
PLAT=hikey \
BL33=u-boot.bin \
SCP_BL2=mcuimage.bin \
TRUSTED_BOARD_BOOT=1 \
MBEDTLS_DIR=../../mbedtls \
GENERATE_COT=1 \
