watchdog: ziirave_wdt: Fix JUMP_TO_BOOTLOADER payload
Bootloader firmware expects the following traffic for
JUMP_TO_BOOTLOADER:
S Addr Wr [A] 0x0c [A] 0x01 [A] P
using ziirave_firm_write_byte() will result in
S Addr Wr [A] 0x0c [A] 0x01 [A] 0x01 [A] P
which happens to work because firmware will ignore any extra bytes and
expected magic value matches byte count sent by
i2c_smbus_write_block_data(). Fix this by converting the code to use
i2c_smbus_write_byte_data() instead.
