sfi: table irq 0xFF means 'no interrupt'
commit a94cc4e6c0a26a7c8f79a432ab2c89534aa674d5 upstream. According to the SFI specification irq number 0xFF means device has no interrupt or interrupt attached via GPIO. Currently, we don't handle this special case and set irq field in *_board_info structs to 255. It leads to confusion in some drivers. Accelerometer driver tries to register interrupt 255, fails and prints "Cannot get IRQ" to dmesg. Signed-off-by: Kirill A.
