Subject: [PATCH] media: tea5764: reconcile Kconfig symbol and macro

The Kconfig symbol RADIO_TEA5764_XTAL is unused. The code does use a
RADIO_TEA5764_XTAL macro, but does that rather peculiar. But there seems
to be a way to keep both. (The easiest way out would be to rip out both
the Kconfig symbol and the macro.)

Note there's also a module parameter 'use_xtal' to influence all this.

I didn't dare to submit this a trivial patch. This is still untested. By
the way, is xtal a common abbreviation of crystal?
