[PATCH v1] gpio: stmpe: Simplify with dev_err_probe()

[Shen Lichuan <shenlichuan@xxxxxxxx>]

Use dev_err_probe() to simplify the error path and unify a message 
template.

Using this helper is totally fine even if err is known to never 
be -EPROBE_DEFER.

The benefit compared to a normal dev_err() is the standardized format
of the error code, it being emitted symbolically and the fact that
the error code is returned which allows more compact error paths.
