Sound: ALC5640: Add RealTek 5640 audio codec support for playback

Derived from WM8994 codec files, with some reg values taken from
the Linux kernel sound/soc/codec RT5640 code/headers. Very simple,
only supports playback on HP and speakers.

Works OK on a Tegra T114 Dalmore with E1623 RT5640 audio board.
Note that the RealTek codecs have 2-byte config registers (I2C),
so your I2C driver needs to support multi-byte transfers to
read/write the registers in this device.

BUG=chrome-os-partner:23782
BRANCH=none
TEST=Built all boards that use 'sound' cmd AOK (Exynos5),
no change/errors.
