This patch sanity checks the SMMU context created by the platform
code. The first entry contains the size of the array; which the
driver now verifies before moving on with the save.
This patch also fixes an error in the calculation of the size of
the context that gets copied to TZDRAM.

The TZRAM memory loses its state during "System Suspend". This patch
check if TZRAM base address contains valid data, to decide if the system
is exiting from "System Suspend". To enable TZDRAM encryption, the Memory
Controller's TZDRAM base/size registers would be populated by the BPMP
when the system "wakes up".

This patch adds support to save the BL31 state to the TZDRAM
before entering system suspend. The TZRAM loses state during
system suspend and so we need to copy the entire BL31 code to
TZDRAM before entering the state.
In order to restore the state on exiting system suspend, a new
CPU reset handler is implemented which gets copied to TZDRAM
during boot. TO keep things simple we use this same reset handler
for booting secondary CPUs too.
