Lennert Buytenhek 0b29de4a6a [ARM] 3824/1: iop3xx: add cp6 enable/disable macros 
Add macros to enable and disable access to CP6.  On the iop3xx, enabling
CP6 access unfortunately also enables access to that coprocessor from
unprivileged code, so we need these macros to enable and disable access
to the coprocessor whenever we need to access it.
