Performance: BootReceiver: set CPU min/max freqs before CPU governor

When setting certain combinations of CPU governor/freqs on boot , the
max frequency needs to be changed first in order for some settings to
work correctly.

Example: changing from a default governor of ondemand and frequency
of 1GHz to interactive governor and 1.2GHz frequency , hispeed_freq
will get stuck at 1GHz unless the max frequency is set prior to the
governor.

Adding configurability of frequency cap (min/max) files' path.

This way those devices that have a special path for
frequency caps can overlay it in the given device's
resources for Settings package.
It's defaulting to the general paths that are used
in most of the kernels.
It's usable for example in endeavoru device tree
where the max cap can only be set through
a different sys path.
