refactor(platforms): remove usage of psci_power_down_wfi

The callers in PSCI will now call wfi() after calling the
pwr_domain_pwr_down() platform hook (previously they were mutually
exclusive). As such, there is no need for platforms to do this
themselves. In fact, it is strongly advisable for platforms not to do
this themselves so that the PSCI can apply any relevant errata
mitigations.

refactor: panic after calling psci_power_down_wfi()

This function doesn't return and its callers that don't return either
rely on this. Drop the dead attribute and add a panic() after it to make
this expectation explicit. Calling `wfi` in the powerdown sequence is
terminal so even if the function was made to return, there would be no
functional change.

This is useful for a following patch that makes psci_power_down_wfi()
return.
