[PATCH] gpio: add MODULE_DEVICE_TABLE

[Axel Lin <axel.lin@gmail.com>]

The device table is required to load modules based on modaliases.
After adding MODULE_DEVICE_TABLE, below entries will be added to modules.pcimap:

pch_gpio             0x00008086 0x00008803 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0
ml_ioh_gpio          0x000010db 0x0000802e 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0
