gpio/omap: Remove bank->id information and misc cleanup 



The driver does not need anymore any id to identify the GPIO instance.
Remove every occurence of the bank->id inside the driver.

Remove two trailing spaces.
Add a dev variable for better readability in probe.
Remove unused variable bank->pbase.
