The gpiod table was added without any usage making it unused
as reported by Clang compilation from omap1_defconfig on linux-next:

arch/arm/mach-omap1/board-h2.c:347:34: warning: unused variable 'isp1301_gpiod_table' [-Wunused-variable]
static struct gpiod_lookup_table isp1301_gpiod_table = {
                                 ^
1 warning generated.

The patch adds the missing gpiod_add_lookup_table() function.

Looks consistent to me with other callers of gpiod_add_lookup_table
from .init_machine callbacks.
