SSM260x also supports 16kHz with external master clocks of 12.000MHz, 12.288MHz and 18.432MHz. Add matching coefficients, update constraints and announced rates.

patch against topic/ssm2602 of kernel.org/.../broonie/sound.git Values taken from SSM2603 datasheet (2602/2603/2604 identical here). Tested on real hardware with 12.288MHz master clock. Useful e.g. for wideband codecs like G.722.
