Dynamic_config: remove the FVP dtb files ...

Since FVP enables dynamic configuration by default, the DT blobs are
compiled from source and included in FIP during build. Hence this
patch removes the dtb files from the `fdts` folder.

zynqmp: Fix EG/EV detection logic ...

The vcu disable bit in efuse ipdisable register is valid
only if PL powered up so, consider PL powerup status for
determing EG/EV part. If PL is not powered up, display
EG/EV as a part of string. The PL powerup status will
be filled by pmufw based on PL PROGB status in the
9th bit of version field.This patch also used IPI
to get this info from pmufw instead of directly accessing
the registers. Accessing this info from pmufw using
IPI fixes the issue of PMUFW access denied error for
reading IPDISABLE register.

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.

zynqmp: pm_service: Make PMU IPI-1 channel unsecure ...

PMU IPI-1 is used for callbacks from PMU to master. Unsecure
master can also receive callbacks from PMU, so make PMU IPI-1
as non-secure.

All requests from master(s) to PMU would still go on PMU IPI-1
secure channel.

xilinx: zynqmp: Remove PMU Firmware checks ...

Xilinx now requires the PMU FW when using ATF, so it doesn't make sense
to maintain checks for the PMU FW in ATF. This also means that cases
where ATF came up before the PMU FW (such as on QEMU) ATF will now hang
waiting for the PMU FW instead of aborting.

zynqmp: pm: Allow to set shutdown scope via pm_system_shutdown API ...

psci system_reset and system_off calls now retrieve shutdown scope on
the fly. The default scope is system, but it can be changed by calling
pm_system_shutdown(2, scope)

Until full support for different restart scopes becomes available with
PSCI 1.1 this change allows users to set the reboot scope to match
their application needs.

Possible scope values:
0 - APU subsystem: does not affect RPU, PMU or PL
1 - PS only: shutdown/restart entire PS without affecting PL
2 - System: shutdown/restart applies to entire system

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.

since it clears power down request for specified APU processor.
Move this function out of pm_client_wakeup to allow passing wake up
requests to the PMU for other processor in the system.

is unchanged.

ELs and ensuring that all conditions for power-off suspend mode
are set.
