After fixing all the offending users referencing the global GPIO
numberspace in OMAP1, a few sites still remain including the
legacy <linus/gpio.h> header for no reason.
Delete the last remaining users, and OMAP1 is free from legacy
GPIO dependencies.
Fixes: 92bf78b33b ("gpio: omap: use dynamic allocation of base")
