hatch: refactor gpio table into baseboard, allow empty SPDs
Each variant needed to define variant_early_gpio_table(), even if it didn't need to make any changes. Added a __weak version of the function into baseboard/gpio.c. Certain upcoming Hatch variants will not use SPD files. Allow SPD_SOURCES in spd/Makefile.inc to be empty. BUG=None BRANCH=None TEST=Build coreboot and see that it builds without error Change-Id: Ie946cfd7c071824168faa38fd53bd338a5a451e1 Signed-off-by: Paul Fagerburg <pfagerburg@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/36068 Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
