[PDK-12327] freertos: c66x: port: use TSC counter for runtime calc
- Use TSC counter in C66x CPU for calculating current run time
- This reverts commit c6e34646389c5910fda8e1a2787bcc53a98aff24
"[PDK-10107] FreeRTOS: C66x: Use OS Tick Timer instead of TSC Counter"
which was updated along with R5F so that the portable layer would be
having similar implementation for both ISA.
- Unlike R5F PMU counter halts during wfi(IDLE) mode,
There is no such limitation in C66x to use TSC counter
- Also usage of TSC counter available in the CPU itself will be having
lesser overhead compared to reading DM Timer (OS Tick Timer) registers
each time for run time calculations
- This also fixes PDK-12327 on C66x, FreeRTOS task stats reporting total
CPU load > 100%
