Input: i8042 - add quirk for ASUS Zenbook UX425QA_UM425QA 



The ASUS Zenbook UX425QA_UM425QA fails to initialize the keyboard after
a cold boot.

A quirk already exists for "ZenBook UX425", but some Zenbooks report
"Zenbook" with a lowercase 'b'. Since DMI matching is case-sensitive,
the existing quirk is not applied to these "extra special" Zenbooks.

Testing confirms that this model needs the same quirks as the ZenBook
UX425 variants.
