remoteproc: qcom_wcnss: Fix on platforms without fallback regulators
[ Upstream commit 4ca45af0a56d00b86285d6fdd720dca3215059a7 ]
Recent change to handle platforms with only single power domain broke
pronto-v3 which requires power domains and doesn't have fallback voltage
regulators in case power domains are missing. Add a check to verify
the number of fallback voltage regulators before using the code which
handles single power domain situation.
