refactor(psci): move psci_do_pwrdown_sequence() out of private header

Browse source 
Move the psci_do_pwrdown_sequence() function declaration from PSCI
private header to common header. The psci_do_pwrdown_sequence is
required to support warm reset, where each CPU need to execute the
powerdown sequence.
