Add support for the es7154 which is basically an es7134 with an
embedded power amplifier and lower maximum sample rate

Drop AVDD in favor of PVDD to match the names used in the datasheet
and only claim PVDD on the es7154. The es7134 and es7144 don't have
a separate supply for the digital I/O.

Add the VDD and AVDD power supplies to the DAPM graph as some board may
need to enable a regulator to turn them on.

For each supported sample rate, the es7134 can work with several
mclk / sample rate ratio. Check if ratio we get is actually OK.

64Khz is actually not supported by the es7134 according to the datasheet

Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.

The es7134 is 24bit, 192Khz i2s DA converter for PCM audio.
Datasheet is available here : http://www.everest-semi.com/pdf/ES7134LV%20DS.pdf
This driver is also compatible with the es7144, which is the same as the
es7134, with 2 additional pins for filtering capacitors.
