commit 4e4521f76ff96f83561555f76c50d25314320d10 upstream.

Rename the bindings documentation file for R-Car I2C controller
from i2c-rcar.txt to renesas,i2c.txt.

This is part of an ongoing effort to name bindings documentation files for
Renesas IP blocks consistently, in line with the compat strings they
document.

(dropped unsupported compatible strings. dropped updating MAINTAINERS
file since the entry didnt exist)
