To make ULPI transceiver work, a HIGH - LOW - HIGH pulse needs

are controlled by BOOT_PIN_CTRL register present in CRL_APB
address region. Since CRL_APB can be resticted to secure access,
this pin should be controlled by ATF.

xilinx: zynqmp: pm_service: Fix APU only restart
Existing code blocks each IPI send request in ipi_mb_notify()
function till pmu clears respective bit in ipi observation
register.
After sending PM_SYSTEM_SHUTDOWN request to PMU, PMU will
restart APU. While PMU is restarting APU, ATF is running out
of OCM, which can cause read/write hang from/to OCM.
There is no need to wait for notification from PMU in case
of SystemShutdown request in ATF, as APU is going to restart.
This patch fixes APU only restart issue.
