SPI SWE: clear any pending boot-time interrupts in spi_init()
Charger plug/unplug hw logic in the Iota ABB has no built-in debouncing,
thus electrical contact bounce on the charging power connection interface
produces a lot of charger plug/unplug interrupts. When we boot in
charging mode (charging power present at boot time and is presumably
the cause of Switch-ON), some bounce may occur between the initial
Iota Switch-ON action and Calypso firmware booting. By clearing any
accumulated ITSTATREG interrupts on boot, we prevent these pre-boot
interrupts from generating charger plug/unplug events to FCHG, which
would upset smooth from-boot charging.
