Move all information related to a Secure Partition to the struct
secure_partition_context_t.

This requires an in-depth refactor because most of the previous code of
SPM relied on global information.

This function can be currently accessed through the wrappers
cm_init_context_by_index() and cm_init_my_context(). However, they only
work on contexts that are associated to a CPU.

By making this function public, it is possible to set up a context that
isn't associated to any CPU. For consistency, it has been renamed to
cm_setup_context().

Ensure read and write of flags defined in the console struct are 32 bit

From TF-A v1.5, FVP supports loading the kernel FDT through
firmware as part of dynamic configuration feature. This means
that the FDT no longer needs to be loaded via Model parameters.
This patch updates the user guide to reflect the same.

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.

Xilinx platform mangement related changes

In 'console_set_scope' and when registering a console, field 'flags' of
'console_t' is assigned a 32-bit value. However, when it is actually
used, the functions perform 64-bit reads to access its value. This patch
changes all 64-bit reads to 32-bit reads.

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.

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.

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.

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
