Special handle:
Once the BCB offset changes, reinitialize "boot_mode".
Background:
1. there are two Android BCB at the 0x00 and 0x20 offset in
misc.img to compatible legacy(0x20) SDK.
2. android_bcb_msg_sector_offset() is for android image:
return 0x20 if image version < 10, otherwise 0x00.
3. If not android image, BCB at 0x20 is the valid one.
U-Boot can support booting both FIT & Android image, if FIT
boot flow enters here early than Android, the "boot_mode" is
set as BOOT_MODE_RECOVERY according to BCB at 0x20 offset.
After that, this function always return static variable "boot_mode"
as BOOT_MODE_RECOVERY even android(>=10) boot flow enter here.
