Since the driver da9121-regulator depends on CONFIG_OF,
it makes no difference to wrap of_match_ptr() here.
Remove of_match_ptr() macros to clean it up.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

When an i2c remove callback fails, the i2c core emits a generic error
message and still removes the device. Apart from the message there the
return value isn't further used.
So don't return an error code after having already emitted a driver
specific warning about the problem to prevent two messages about the
same issue.

This patch fixes identification of DA913x parts by the DA9121 driver,
where a lack of clarity lead to implementation on the basis that variant
IDs were to be identical to the equivalent rated non-automotive parts.
There is a new emphasis on the DT identity to cope with overlap in these
ID's - this is not considered to be problematic, because projects would
be exclusively using automotive or consumer grade parts.

There is a missing "return ret;" on this error path so we call
"da9121_check_device_type(i2c, chip);" which will end up dereferencing
"chip->regmap" and lead to an Oops.
