firmware-samsung-pxa1908: install all firmware files unconditionally

It has been found that the calibration files, while not mandatory, could
be useful with the mainline mwifiex driver as well. Install those on
mainline as well and leave the -downstream subpackage as a stub for
-downstream-openrc.

Also, switch from installing the firmware to /usr/lib instead of /lib to
suppress warnings.
