tea5767 has several possible configurations. Before the patch, the driver were assuming the more common configuration. However, some newer cards, like MSI @nyware Master requires other configurations, like de-activating a gpio port and changing chip Xtal. This patch adds the capability of altering device configuration at runtime. This may also be used later to activate some features like auto-mute when signal is weak.
