[media] cx88.rst: Update the documentation

This doc is outdated, and contains information that it is not
true anymore. Update it to reflect the changes that this
driver suffered since I started working on it.

While here, also update Gerd's name.

 This is a v4l2 device driver for the cx2388x chip.

 video
-	- Basically works.
-	- For now, only capture and read(). Overlay isn't supported.
+	- Works.
+	- Overlay isn't supported.
 
 audio
-	- The chip specs for the on-chip TV sound decoder are next
-	  to useless :-/
-	- Neverless the builtin TV sound decoder starts working now,
-	  at least for some standards.
-	  FOR ANY REPORTS ON THIS PLEASE MENTION THE TV NORM YOU ARE
-	  USING.
-	- Most tuner chips do provide mono sound, which may or may not
-	  be useable depending on the board design.  With the Hauppauge
-	  cards it works, so there is mono sound available as fallback.
+	- Works. The TV standard detection is made by the driver, as the
+	  hardware has bugs to auto-detect.
 	- audio data dma (i.e. recording without loopback cable to the
 	  sound card) is supported via cx88-alsa.
 
 vbi
-	- Code present. Works for NTSC closed caption. PAL and other
-	  TV norms may or may not work.
+	- Works.
