[PATCH] adc:cpcap-adc: Fix IRQ flags for using threaded handler

[venkat.prashanth2498@gmail.com]

From: Venkat Prashanth B U <venkat.prashanth2498@gmail.com>

Mark the request with ONESHOT using IRQF_ONESHOT.

Semantic patch information:
threaded IRQs without a primary handler need to be
requested with IRQF_ONESHOT, otherwise the request
will fail.
So pass the IRQF_ONESHOT flag in this case.
