Add support for the Qualcomm QCS404 platform that contains v1 of the TSENS
IP. Introduce a fallback binding to handle "v1" functionality.

These patches apply on top of previous tsens-related patches sent to the
list pending merge along with various qcs404 patches under review
(available in this branch[1] for convenience).

Andy,

These have dependency on the patch series adding The DT file I sent
yesterday[1]. Please apply these on top of that series
