[PATCH] Fix Asus B2402FBA internal keyboard and track point

[Stefan Blum <stefanblum2004@gmail.com>]

By default the internal keyboard and track point on the Asus Expertbook
B2 Flip B2402FVA are not functional.

Similar to the Asus board B2402FBA, on the B2402FVA the internal keyboard
is only functional by adding it to the irq1_level_low_skip_override array.

For the internal elan track point, i have found out that setting the class to
MT_CLS_WIN_8_FORCE_MULTI_INPUT_NSM makes the track point function as expected.
