MGS-4868 [#ccc] enable userspace register read

In v6.2.4, userspace register access was controlled by defining
gcdREGISTER_ACCESS_FROM_USER, enabled by default.

This changed in v6.4.0 where gcdREGISTER_ACCESS_FROM_USER is replaced by
gcdREGISTER_READ_FROM_USER and gcdREGISTER_WRITE_FROM_USER,
both disabled by default.

For the moment, gputop uses userspace register access ioctl to
read the GPU performance counters.
