Instead of polling at 100ms intervals for register writes, poll at 5ms
intervals. This is consistent with the xc5000 specification, and improves
tuning time by up to 500 ms on devices that such as the au0828 which do not
properly implement i2c clock stretching (since the five register writes that
occur for a tuning request often do not complete immediately but do complete
far before 100ms has gone by).
The net amount of time we wait before timing out is unchanged (500ms).

Defer loading of the xc5000 firmware until it is actually needed. This helps
on distros that have hald, which results in the device not being available
for use for around ten seconds in cases where the i2c bus is slow (such as
the HVR-950Q). Also, the firmware load isn't really useful since we
immediately put the device to sleep afterward, which means a firmware reload
will be required anyway.

Bring back the code that puts the xc5000 to sleep. For the Pinnacle 801e
this results in power consumption at idle dropping from 325ma to 124ma.
If there are *actually* any devices that don't work in this configuration,
they should set dvb_frontend.ops.tuner_ops.sleep to NULL (per mkrufky's
suggestion)
Also, had to make sure we were making sure the firmware was loaded in the
digital version of set_params, or else we end up get i2c errors if the

The GPIO's on the product can be in one of three places. To date we've
mainly used the GPIO's on the bridge itself, and once on the encoder.
Rather than having the complexity of multiple GPIO writes/reads from
isolated placed in the driver we'll route them through this function,
so we can make intelligent decisions about 1) Where the GPIO lives
and 2) Whether it conflicts (based on board) with some other function
to avoid bugs.

must stop doing so.
For pvrusb2, I propose the following change, which should lead to an
