arm: vt8500: Fix build warning in uncompress.h
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. Signed-off-by: Tony Prisk <linux@prisktech.co.nz> Signed-off-by: Olof Johansson <olof@lixom.net>
