Use board define BOARD_RECOVERY_BLDRMSG_OFFSET with a decimal integer
to define a custom offset where the bootloader message should be
read/written.

When set_bootloader_message_block() is called, it fopens /misc in write
binary mode, wiping all contents other than what is being written. The
bootloader msg structure is only 1024+32+32 bytes, so some manufacturers
store more than just a bootloader msg on /misc. fopen in read+append
mode so that only the bootloader msg is written and the rest of the
partition is left untouched.
