Set the iio device's name based on the chip used for the
LTC2499 only. The most common way for IIO clients to interact
with a device is to address it based on it's name. By using
the dev_name() function, the name will be set based on a
i2c_client's kobj name, which has the format i2c_instance-i2c_address
(1-0076 for example). This is not ideal, since it makes a
requirement for userspace to have knowledge about the hardware
connections of the device.
The name field is set to NULL for the LTC2497 and LTC2496, so
that the old name can kept as it is, since changing it will
result in an ABI breakage.

The macro prevents use of driver with ACPI PRP0001 and
the of_match_id structure is defined in mod_devicetable.h so include
that directly rather than of.h.
Note this is mostly about removing something I don't want cut and
paste into new drivers rather than expectation that this particular
driver will be used on an ACPI platform.

This chip is similar to the LTC2497 ADC, it just uses SPI instead of I2C
and so has a slightly different protocol. Only the actual hardware
access is different. The spi protocol is different enough to not be able
to map the differences via a regmap.
Also generalize the entry in MAINTAINER to cover the newly introduced
file.
