[PATCH 3/5] Input: aw86927 - add support for Awinic AW86937

[Qianhui Xu]

The AW86937 reports CHIPID 0x9370 and is register compatible with the
AW86938 as far as the boost setup is concerned, so it joins that branch of
the haptic initialisation.  Detection stays by CHIPID, so the existing
AW86927 compatible keeps working as fallback.
