imx: mx27 move GPIO_PORTx to gpio.h
These GPIO_PORTx macros should be in gpio.h, but not in imx-regs.h. Also, imx-regs.h and iomux-v3.h has same macro defintion for GPIO_PORTx, and both of them are included in mxc_i2c.c(include mxc_i2c.h). This will incur build warnings with macro redefinition. Since iomux-v3.h is not compatible with mx27, we can not simply include iomux-v3.h for mx27, so move the GPIO_PORTx to gpio.h to fix the build warning.
