[PATCH 2/3] ASoC: support all possible sample rates in the WM8776 driver

[Timur Tabi <timur@freescale.com>]

ASoC codec drivers can use the .set_sysclk function to dynamically specify
the list of support sample rates, because that list is often based on
the input clock frequency.  Although the WM8776 includes a .set_sysclk
function, it was also hard-coding the supported sample rates to a list
that depends on a specific input clock frequency.

So change the hard-coded list to a range within the capabilities of the
WM8776 itself, and let wm8776_set_sysclk() do its job.
