<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">spec/*: Clean up fast idle configure option</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">The CLOCK_DRIVER_USE_FAST_IDLE configure option is implemented
in the shared clock driver implementation. Unfortunately, the spec
files scattered the yaml to enable it for a specific BSP. This
change adds the shared file spec/build/bsps/optclkfastidle.yml which
is now the only place the CLOCK_DRIVER_USE_FAST_IDLE is specified.
That file includes a master list of BSPs which are known to be able to
run on simulators that are slow enough to benefit from this option.</p>
<p dir="auto" style="color: #3a383f; margin: 0;" align="initial">As a point of information, the entire riscv BSP family can run on
both spike and qemu. None had the option do use fast idle. With this
option enabled, the time taken for a full test run on spike for
rv32i and rv64imadfc dropped by ~45%.</p>
