pinctrl: sunxi: Fix SPDIF function name for A83T

commit 7903d4f5e1dec53963cba9b1bc472a76a3532e07 upstream.

We use well known standard names for functions that have name, such as
I2C, SPI, SPDIF, etc..

Fix the function name of SPDIF, which was named OWA (One Wire Audio)
based on Allwinner datasheets.
