It look like a copy-paste bug that the twl_driver name
was used.
Rename to the more sensible mtl_driver

Since regulator_get() can return an errno via regulator pointer, we
need to make sure we handle that case without passing bogus pointers
around.
Add code to convert mtl017->regulator to a dummy regulator if
regulator_get() fails.

Add macro and dependency to avoid boilerplate code. Since now simple
i2c drivers only have to include the i2c.h header and call the
device_i2c_driver() macro to register a i2c device driver.

The MTL017 is found on the Efika Smartbook. Not much is known about
this chip, so this driver only programs a register dump which is suitable
for some panels.
