V4L/DVB (5774a): Remove CONFIG_BIGPHYS_AREA from zoran_driver

Browse source 
CONFIG_BIGPHYS_AREA is an out-of-tree kernel patch. It makes no sense to 
keep supporting this on mainstream.

The out-of-tree compilation with CONFIG_BIGPHYS_AREA will still be
preserved at the v4l-dvb development tree at:
	http://linuxtv.org/hg/v4l-dvb
