snd_akm4xxx_init() clears the register and volume caches before
dispatching by codec type. The AK5365 case then returns immediately,
leaving the software cache at zero instead of the documented AK5365
reset defaults.

The AK5365 capture volume controls read from volumes[] and the proc
register dump reads from images[], so the initial capture volume state
and proc output are wrong until a control write happens.

Seed the AK5365 cache with its documented reset defaults instead of
adding a guessed init sequence. The datasheet documents the reset
values and states that MCLK/LRCK changes do not require a PDN/PWN
reset because the chip has a built-in reset-free circuit.
