It's almost same, but one firmware was loaded in I2C mode as one I2C device
was probed, and operate slavers by address. And with SPI mode, we probe two
SPI devices in current case, so will load two firmware binary, and some
operation need to be processed as special case, for example, under SPI,
read need one byte shifted if page number is large than 1.
