soc: fsl: qe: make cpm_muram_free() return void

Browse Source 
Nobody uses the return value from cpm_muram_free, and functions that
free resources usually return void. One could imagine a use for a "how
much have I allocated" a la ksize(), but knowing how much one had
access to after the fact is useless.
