V4L/DVB (5166): Remove obsolete alias defines of CONFIG_* settings

The out of tree v4l-dvb build system didn't always override the kernel's
configuration settings with v4l-dvb's settings correctly.  To work around
this, makefiles would define some new macro based on the setting of a
config variable.  e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if
CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this
is no longer necessary.  This patch gets ride of these extra defines and
just uses the CONFIG_* settings directly.
