Introduce devm_cpm_muram_alloc() and devm_cpm_muram_alloc_fixed(), the
resource-managed version of cpm_muram_alloc and cpm_muram_alloc_fixed().

These resource-managed versions simplify the user avoiding the need to
call cpm_muram_free(). Indeed, the allocated area returned by these
functions will be automatically freed on driver detach.
