staging: vchi: Remove ARM64 from TODO list 



ARM64 for core vchiq which is the core of vc04_services should
now be work complete.  The driver compiles without any errors
or warnings, and works just as well as 32 bit mode.  The
necessary compatibility wrappers for the 32 bit ioctls have been
written and merged.

Since no more ARM64 specific changes should be needed, perhaps
it's best to remove it from the TODO list.

This driver won't be very useful unless we also have it working on

Raspberry Pi 3.  This requires, at least:



  - Figure out an alternative to the dmac_map_area() hack.



  - Decide what to use instead of dsb().



  - Do something about (int) cast of bulk->data in

    vchiq_bulk_transfer().



    bulk->data is a bus address going across to the firmware.  We know

    our bus addresses are <32bit.



2) Write a DT binding doc and get the corresponding DT node merged to

This will let the driver probe when enabled.
