iMX51: introduce IMX_GPIO_NR
Currently, to define a GPIO number, we're using something like :
#define EFIKAMX_PCBID0 (2*32 + 16)
to define GPIO 3 16.
This is not really readable and it's error prone imho (note the 3 vs 2).
So, I'm introducing a new macro to define this in a better way. Now, the
code sample become :
#define EFIKAMX_PCBID0 IMX_GPIO_NR(3, 16)
v2:
- move to gpio.h
- add parens & spaces
- switch to IMX_GPIO_NR instead of MX51_GPIO_NR
