[ARM] fix AT91 include loops 

AT91 has one include loop in its header files:

  include/asm-arm/io.h <- include/asm-arm/arch-at91/io.h <-
   include/asm-arm/io.h

Circular include dependencies are dangerous since they can result in
inconsistent definitions being provided to other code, especially if
'#ifndef' constructs are used.

Solve this by removing the offending includes.  Built tested using my
AT91 configuration.
