tools/power turbostat: Increase the limit for fd opened
When running turbostat, a system with 512 cpus reaches the limit for
maximum number of file descriptors that can be opened. To solve this
problem, the limit is raised to 2^15, which is a large enough number.
Below data is collected from AMD server systems while running turbostat:
|-----------+-------------------------------|
| # of cpus | # of opened fds for turbostat |
|-----------+-------------------------------|
| 128 | 260 |
|-----------+-------------------------------|
| 192 | 388 |
|-----------+-------------------------------|
| 512 | 1028 |
|-----------+-------------------------------|
So, the new max limit would be sufficient up to 2^14 cpus (but this
also depends on how many counters are enabled).
