Mauro Carvalho Chehab 0e1165e8d0 V4L/DVB (6385): Adds the capability of configuring tea5767 support
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.
