[PATCH] arch/arm: use simple i2c probe function

From: Stephen Kitt
Date: Fri Aug 07 2020 - 11:40:59 EST


The i2c probe functions here don't use the id information provided in
their second argument, so the single-parameter i2c probe function
("probe_new") can be used instead.

This avoids scanning the identifier tables during probes.
