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
