[PATCH] gpio/mxc: fix a bug with gpio_get_value calling

[Shawn Guo]

When calling gpio_get_value, the gpio number other than bit offset
should be passed as the argument.

Grant, Sascha,

This is an important bug fix.  Currently, if any driver request 
any gpio not on port 1 for IRQ_TYPE_EDGE_BOTH, we run into kernel
oops.  So please apply the patch asap.  Thanks.
