[PATCH 2/3] ASoC: adau1977-spi: drop __maybe_unused and of_match_ptr()

[Alvin Šipraga]

Since commit 5ab23c7923a1 ("modpost: Create modalias for builtin
modules") MODULE_DEVICE_TABLE() is enough to reference a match table and
the data isn't discarded by the linker even when the driver is built-in
and CONFIG_OF is disabled. Drop the of_match_ptr() wrapping so that OF
matching keeps working regardless of CONFIG_OF. This also means we can
drop __maybe_unused since it's always used.

The entries in adau1977_spi_of_match were also erroneously indented with
spaces - replace the indentation with tabs to conform with coding style.
