[PATCH 1/2] staging: wilc1000: remove unused interrupt status handling code

[Ajay.Kathat at microchip.com]

From: Ajay Singh <ajay.kathat at microchip.com>

Remove interrupt handling for unused interrupt status(PLL update and
Sleep). The firmware only initiates the interrupt for the data transfer
to host and rest are not used anymore.
