ASoC: cs35l56: Create debugfs files for factory calibration

Browse source

Create debugfs files that can be used to perform factory calibration.

During manufacture, the production line must perform a factory calibration
of the amps. This patch adds this functionality via debugfs files.

As this is only needed during manufacture, there is no need for this to be
available in a normal system so a Kconfig item has been added to enable
this. The new Kconfig option is inside a sub-menu because items do not
group and indent if the parent is invisible or there are multiple parent
dependencies. Anyway the sub-menu reduces the clutter.
