Subject: [RFC PATCH 0/2] wm8960: Relax bit clock computation

This patch series allows running S20_3LE encoded samples on wm8960 codec.

First patch does a small refactoring of sysclk frequency search because
wm8960_configure_sysclk was getting pretty convoluted.

The second patch allows relaxing bitclock computation in the way that
if an exact bitclk couldn't be derived from sysclk it chooses the
smalles available bitclk greater than the desired bitclk.

For a better reviewing experience you can checked the squashed version

Note that this is a follow up of:

"ASoC: wm8960: Use physical width for bclk"
