platform/x86: x86-android-tablets: Constify the gpiod_lookup_tables a…

…rrays

The individual gpiod_lookup_table structs cannot be const because they
contain a list-head which gets used when registering them.

But the array of pointers to the gpiod_lookup_table-s used by a board
can be const, constify these.
