mkbp: Fix vup/vdn button code mixups
MKBP driver seems to have two mixups with the vup/vdn button codes.
1. Button codes used for vup/vdn in enum Buttons does not match the
codes used by vboot library.
2. button_scancodes array is expected to define codes in the same
order as MKBP button event definitions.
Because of the above two errors, we got lucky with vup/vdn usage
i.e. when vup button was pressed, it used button_scancode for vdn from
button_scancodes array and when this was reported back to vboot it
used the wrong code i.e. code for vup. Two negatives ended up making a
positive.
This change fixes the button_scancodes index and the code value for
vup and vdn.
