Sean Khan 849ebc905b qualcommax: enhance smp_affinity (log, uci, syntax)

1.) Changed logic of `set_affinity` to now use physical cores rather than
    knowing the bitmask. Rather than having to know a bitmask, users can
    provide a numerical instance of one or more CPU cores
    (numbered 0-63).

    This is done via function `cpus_to_bitmask`.

    Functions Added:

    a.) bitmask_to_cpus - Takes a bitmask of CPUs and returns a
         list of CPU numbers. (i.e. `bitmask_to_cpus "f"` -> 0,1,2,3)

    b.) cpus_to_bitmask - Takes a comma/space or range list of CPUs and returns
         a bitmask.

         Example:
         `cpus_to_bitmask "2,3"`     -> c
         `cpus_to_bitmask "0,1,2,3"` -> f
         `cpus_to_bitmask "1,3"`     -> a

         With or without quotes
         `cpus_to_bitmask "1 3"`     -> a
         `cpus_to_bitmask  1 3`      -> a

2.) Added UCI options:

    enable     - to enable/disable the script from running.   [default 1 (on)]
    enable_log - to enable/disable logging output to `logger`.[default 1 (on)]

    Log output:
