switch-coreboot/superio/ite/it8716f/superio.c
Myles Watson 7c14a50c1c This patch makes all the SuperIOs build again, and reverts some breakage that 
I introduced earlier.

It adds a placeholder in the fintek SuperIO so the array indexing works.
It moves the enable to make the struct more compatible with v2.
