Subject: [PATCH 15/15] ASoC: ops: Apply platform_max after deciding control type

It doesn't really make sense for the type of a control to change based
on the platform_max field. platform_max allows a specific system to
limit values of a control for safety but it seems reasonable the
control type should remain the same between different systems, even
if it is restricted down to just two values. Move the application of
platform_max to after control type determination in soc_info_volsw().
