Subject: [PATCH] hwdb: 60-keyboard: Fix volume-button mapping on Asus TF103C

The Asus TF103C misses the home button in its PNP0C40 GPIO resources
causing the button mappings for the volume buttons to be off by one,
leading to the volume-up button sending home button presses and the
volume-down button sending volume-up button presses.

Add a 60-keyboard hwdb entry to correct the mappings. Note this is
split over 2 input devices because the soc_button_array driver
creates separate input devices for power + home and vol up/down.
This is done because power/home act as wakeup buttons where as
the volume buttons do not.

This means that after this fixup the home -> volume-up button
still acts as a wakeup button, there is nothing which can be done
about this without adding a kludge to the kernel which is not
worth the trouble (IMHO).

(cherry picked from commit 04b457d8ef9c93be3b2048c6f545cdbcf1b893a1)
