V4L/DVB (8098): xc5000: add module option to load firmware during driver attach
The xc5000 firmware download process can be slow on certain devices.
Add a module option, "init_fw" to perform the firmware download during
xc5000_attach(), which would get the firmware download over with well
before any tune request is made.
When this option is enabled, it will reduce the time it takes to get a
signal lock during the first tune after driver load, but will add a few
seconds to the driver initialization.
