spi: dw: Disable all IRQs when controller is unused 
It's a good practice to disable all IRQs if a device is fully unused. In
our case it is supposed to be done before requesting the IRQ and after the
last byte of an SPI transfer is received. In the former case it's required
to prevent the IRQ handler invocation before the driver data is fully
initialized (which may happen if the IRQs status has been left uncleared
before the device is probed). So we just moved the spi_hw_init() method
invocation to the earlier stage before requesting the IRQ. In the later
case there is just no point in having any of the IRQs enabled between SPI
transfers and when there is no SPI message currently being processed.
