[PATCH v2025.09.y 45/49] i2c: omap: fix probe on am335x

[Ahmad Fatoum]

The AM335x uses ti,omap4-i2c as compatible for the I2C device tree
nodes, but that compatible unlike its brethern has no driver data as
it's determined using the machine compatible in the probe function
instead.

device_get_match_data() returning NULL is thus expected and should not
lead to an immediate error.

Fixes: 20d87123a638 ("treewide: replace dev_get_drvdata with device_get_match_data")
