All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

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.

This fix modifies the order of system includes to meet the ARM TF coding
standard. There are some exceptions to this change in order to retain
header groupings and where there are headers within #if statements.

During system suspend, identify slaves which are configured
as wake sources and call pm_set_wakeup_source API for each of them.

Identifying if device may wake the system is done by checking if any
interrupt of that device is enabled in GICD_ISENABLER when the APU is
about to enter SUSPEND_TO_RAM state. If such interrupt is found,
pm_set_wakeup_source is called with corresponding PM node ID as
argument.
