trusty: Require dynamic translation tables

Trusty requires dynamic translation tables support, so the makefile of
Trusty itself should request it. Not doing so causes platforms such as
FVP to fail to build with Trusty. Other platforms like Tegra still build
because they use dynamic translation tables by default.

Tegra: support for System Suspend using sc7entry-fw binary

be supported on Tegra210 platforms and its functionality will be
divided across the CPU and sc7entry-fw.

The sc7entry-fw takes care of performing the hardware sequence required
to enter System Suspend (SC7 power state) from the COP. The CPU is required
to load this firmware to the internal RAM of the COP and start the sequence.
The CPU also make sure that the COP is off after cold boot and is only
powered on when we want to start the actual System Suspend sequence.

The previous bootloader loads the firmware to TZDRAM and passes its base and
size as part of the boot parameters. The EL3 layer is supposed to sanitize
the parameters before touching the firmware blob.

To assist the warmboot code with the PMIC discovery, EL3 is also supposed to

Commit 033648652f ("Make TF UUID RFC 4122 compliant") changed the scanf
parsing string to handle endianness correctly.
However that changed the number of items sscanf handles, without

Increase the expected return value from 11 to 16 to let fiptool handle
