Sphinx reports htmldocs warning:

I have to fix up the bitmask list:

Write the bitmask of bits to clear:
- 1 = clear bit 0 (desired performance excursion)
- 2 = clear bit 1 (minimum performance excursion)
- 3 = clear both bits

The platform sets these bits; OSPM can only clear them.
This file is only present if the cppc-cpufreq driver is in use.
Thanks.
