72ba450562 iio: dac: ad5592r: Make ad5592r_remove() return void 
Up to now ad5592r_remove() returns zero unconditionally. Make it return
void instead which makes it easier to see in the callers that there is
no error to handle.

Also the return value of i2c and spi remove callbacks is ignored anyway.

23636b479a iio:dac:ad5592r: Drop of_match_ptr and ACPI_PTR protections. 
These result in a very small reduction in driver size, but at the
cost of more complex build and slightly harder to read code.
In the case of of_match_ptr it also prevents use of PRP0001
ACPI based identification.  In this particular case we have
a valid ACPI/PNP ID that I am assuming was issued by Analog
Devices.  That should be used in preference to PRP0001 but doesn't
mean we should prevent that route.

This module is related to AD5592R, not AD5593R, so be consistent in naming.
