soc: intel_adsp/ace: fix assert for uncached pointer

Browse source 
Only when CONFIG_MP_MAX_NUM_CPUS > 1, then .bss is put in
uncached region. Otherwise, .bss is in cached region.
So the assertion that g_key_read_holder must be in uncached
region must take into account how many CPUs are enabled on
build.
