package/freescale-imx/firmware-imx: fix the VPU firmware location

Browse Source 
The mainline kernel searches the coda VPU firmware inside the following
locations [1]:

/lib/firmware/
/lib/firmware/vpu/

Currently Buildroot installs the coda firmware into /lib/firmware/imx/vpu,
which is not a valid location.

Fix it by installing the coda firmwares into /lib/firmware/vpu/ which
is a valid path for both mainline and NXP vendor kernels. Also create a
symlink to /lib/firmware/ so that mainline kernels do not need to wait
more than 60 seconds to search again inside /lib/firmware/vpu/.
