[PATCH v2] arm: vt8500: Fix build warning in uncompress.h [for 3.7]

Sun Oct 7 16:56:45 EDT 2012
This removes a build-time warning in uncompress.h due to incorrectly
cast values being passed to readb/writeb.
Removed arm/io.h and readb/writeb. Read/write directly to the serial
port with a volatile pointer.
