[PATCH] bios: pnp move pnp_control_field into pnp_test1 and add constifications

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The scope of array pnp_control_field is limited to just function pnp_test1
so move it into the function. Also add some constifications to read-only
objects.
