Filip Drazic 0b3a4e414b zynqmp: pm: Decode start address related SMC arguments for pm_req_wakeup
The pm_req_wakeup PM API accepts start address (64-bit unsiged integer)
and a flag stating if address should be used. To save an argument
of the SMC call, flag is encoded in the LSB of the address, since
addresses are word aligned.
Decode start address and use-address flag in the PM SMC handler and
pass them to pm_req_wakeup.

Siva Durga Prasad Paladugu 34c571392e zynqmp: pm: Add support for setting suspend-to-RAM mode
Beside standard suspend-to-RAM state, Zynq MPSoC supports
suspend-to-RAM state with additional power savings, called
power-off suspend-to-RAM. If this mode is set, only NODE_EXTERN
must be set as wake source. Standard suspend-to-RAM procedure
is unchanged.

This patch adds support for setting suspend mode from higher
ELs and ensuring that all conditions for power-off suspend mode
are set.
