[Ajay Kumar]

INT_CTL register contains bits INT_POL0 and INT_POL1, and not INT_POL.
This patch fixes the wrong register setting for INT_CTL.

Why are the bit definitions the same???
INT_POL1 uses 1st bit of DP_INT_CTL register.

Please fix this bug as below.

#define INT_POL1				(0x1 << 1)
#define INT_POL0				(0x1 << 0)

Ajay,
please don't make careless mistake.
I don't want to waste my time.
