Currently, the IDs used in PLM CMD header are mixed with SMC IDs in
TF-A which is restricting the range of IDs that can be used by PLM.
Also, the SMC call from firmware driver is passing all 7 32-bit
words in request but TF-A is not passing all of them to firmware and
TF-A passes only 4 32-bit words from firmware to Linux in response.
So, update TF-A to passthrough all PLM commands by having a single
fixed SMC ID for all PLM commands and keep the PLM header in subsequent
SMC arguments. Also, enhance size of payload argument count to support
maximum payloads in request and response buffers to transmit all the
IPI command properly.

Send subsystem restart notification to firmware when TF-A receives
system reset PSCI call. On receiving subsystem restart call, firmware
will send CPU idle callback to TF-A for powering down all cores. Wait
for CPU idle callback from firmware and raise power down request to
all cores after it receives CPU idle callback to power down core.

Add redundant macro call to increase security by making
code glitch immune as security operations might be
called with the IPI command.
