Don't ship GTA02v5 without the rework

[Fahrstuhl]

Heya,
the wiki-page about the Freerunner hardware states that issue would be 
resolved in the GTA02v5 mass production phones. [1]
	"A6 will be fine tune version of A5, only minor schematic change for 
better product quality and version control. Capacitor and resistor 
change A6 also on mass production A5"
