Subject: [PATCH] DVB Optimization: enable gate in a symmetric/disciplined way,
 rather than implementing different ways leading to confusion.

This allows multiple gate_enable/disable's in the tuner read/write
functions, thereby lesser number of I/O operations throughout,
eventually leading to better results. As a side effect for the demods
that detect the STOP bit for auto closing, the auto closing of the
gate can be avoided, thereby a minimal gain in disabling the auto detect
feature as well. Improves readability on the device control.
