misc: mic: host: mic_intr: Properly document function arguments

mic_interrupt() and mic_setup_msix() have incomplete documentation.

Fixes the following W=1 kernel build warnings:

 drivers/misc/mic/host/mic_intr.c:42: warning: Function parameter or member 'irq' not described in 'mic_interrupt'
 drivers/misc/mic/host/mic_intr.c:42: warning: Function parameter or member 'dev' not described in 'mic_interrupt'
 drivers/misc/mic/host/mic_intr.c:188: warning: Function parameter or member 'pdev' not described in 'mic_setup_msix'
