Input: i8042 - add Intel D845PESV to nopnp list

This patch introduces i8042_dmi_nopnp_table to make it possible to perform
DMI matches for systems that need 'i8042.nopnp' to work correctly, and
introduces such an entry for Intel D845PESV -- this system doesn't
detect PS2 mouse reliably without this option, as reported by Robert
Lewis.
