Add optional support for real-time clint
This patch adds optional support clint timer incrementing at
real-time rate. This can be enabled by passing command line
parameter "--real-time-clint".
This feature can be used for:
1. Checking whether any code addition to Spike is slowing down
simulation too much
2. Comparing run-time for software on Spike with other functional
simulators (such as QEMU)
