devfreq_boost: Update and expand to handle CPUBW/LLCCBW boosting

This will enable us to more accurately replicate Pixel 4 userspace DDR boosting by adding support for both CPUBW and LLCCBW devices. https://android.googlesource.com/device/google/coral/+/refs/heads/master/init.power.rc https://android.googlesource.com/device/google/coral/+/refs/heads/master/powerhint.json Signed-off-by: idkwhoiam322 <idkwhoiam322@raphielgang.org> [@0ctobot: Squash idkwhoiam322/weeb_kernel_oneplus_sm8150@86761ff with idkwhoiam322/weeb_kernel_oneplus_sm8150@f9ca549. Refactor device naming conventions and registration for improved clarity and consistency, expand to cover kernel-specific boost events] Signed-off-by: Adam W. Willis <return.of.octobot@gmail.com>
