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 commit 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. cs35l56_hda_apply_calibration() has been changed to return an error code that can be reported back through the debugfs write. The original call to this function doesn't check the return code because in normal use it doesn't matter whether this fails - the firmware will default to a safe calibration for the platform. But tooling using the debugfs files might want to know if there was an error.
