firmware: psci: Extend psci_set_osi_mode() to allow reset to PC mode
The current user (cpuidle-psci) of psci_set_osi_mode() only needs to enable the PSCI OSI mode. Although, as subsequent changes shows, there is a need to be able to reset back into the PSCI PC mode. Therefore, let's extend psci_set_osi_mode() to take a bool as in-parameter, to let the user indicate whether to enable OSI or to switch back to PC mode.
