i2c: i2c-msm-v2: Register an interrupt by adding IRQF_NO_SUSPEND

Browse source 
This change registers an interrupt with flag IRQF_NO_SUSPEND,so as
to allow system to not disable the interrupt by suspend_device_irqs().

If any client issues transfer during system suspend/resume time, i2c
should do transfer without any timeout.
