gpio: Replace ARM gpio.h with the common API in include/asm-generic
ARM boards should use the generic GPIO API This means changing gpio to unsigned type Remove the unused gpio_toggle() function which is not part of the API Comment that free should not modify pin state Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Cc: Joe Hershberger <joe.hershberger@gmail.com> fixed merge conflict in da8xx_gpio.c, tegra2_gpio.c, and extended to the new mxs_gpio.c. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Cc: Albert ARIBAUD <albert.u.boot@aribaud.net>
