ucm: add binary configure file parse

Browse source 
with cset command, UCM set kcontrol parameters directly:
    cset "name='<KCONTROL_NAME>' 1<,2,3,...>"
This patch enables UCM to set kcontrol with parameters from
configure file:
    cset-bin-file "name='<KCONTROL_NAME>' <path/to/file>"
where "cset-bin-file" is a newly added keyword alongside of "cset",
to indicate cset with binary data in file.
The binary data in file is parameter for audio DSPs, and it's just
passed by UCM/ALSA as raw data. The data type of parameter elements
must be byte, and the count must matches driver definition.
