[PATCH v7 3/7] iio: adc: mcp3564: Add support for spi-device-addr

Read the generic spi-device-addr property when determining the hardware
device address. Fall back to the deprecated microchip,hw-device-address
property to preserve compatibility with existing device trees.

The device address remains 1 when neither property is present.
