imx-dsp: Rework the install logic [LF-5799]

Replace the firmware name variable with a simpler firmware platform
variable. This allows the logic that removes firmware that is not
for this platform to handle any firmware, not just the main binary.

Also, make the default value of the variable UNDEFINED. Then, if
a new SOC is not properly added to the variable list, the mv will
fail.
