fix(fvp): update system suspend in OS-initiated mode

This patch fixes system suspend in OS-initiated mode by setting the
value of `last_at_pwrlvl` in the `psci_power_state_t` object to
`PLAT_MAX_PWR_LVL`, which otherwise would result in undefined behavior.

This is conditionally compiled into the build depending on the value of
the `PSCI_OS_INIT_MODE` build option.
