Remove CONFIG_BCB_SUPPORT config from BSP u-boot defconfig files.
So that we can eliminate such errors during boot up:

can't find partition: misc, dump the partition table
idx 0, ptn 0 name='gpt' start=0 len=2048
idx 1, ptn 0 name='tos' start=0 len=2047
idx 2, ptn 0 name='all' start=0 len=7864320
idx 3, ptn 0 name='bootloader' start=2 len=4094
idx 4, ptn 1 name='mmcsdb1' start=20480 len=1024000
idx 5, ptn 2 name='mmcsdb2' start=1228800 len=6635520
cannot get the partion info for misc
Cannot find partition 4080
do_raw_read failed, ret 1
read_bootctl, bcb_rw_block read failed
read command failed
