i2c: i2c-msm-v2: set irq flag to IRQF_EARLY_RESUME for i2c 



I2C interrupts get enabled/disabled during transfers,if a
client driver tries to do transfer as part of early system
resume, i2c interrupts may not fire as they are not
registered as EARLY_RESUME IRQ's.

Change is to register interrupt as IRQF_EARLY_RESUME.
