Running optee_test failed because SEC_DRAM0_SIZE is too small. Previous
is 2 MB. We enlarge it to 11 MB for passing the test. Also we reduce
the NS_DRAM0_SIZE from 13MB to 4MB so that the whole section is still
fit in 16MB.

This commit also modified the document to reflect the changes we've
made in code.

Implement minimal interrupt routing functions. All interrupts are
treated as non-secure interrupts to be handled by the non-secure world.

Add note to the documentation about disabling FIQs qhen using OP-TEE
with Linux.

This patch adds support for TBB to rpi3. The ROTPK is generated at build
time and is included into BL1/BL2. The key and content certificates are
read over semihosting.

Support for loading optee images as BL32 secure payload.

Switch to the new console APIs enabled by setting MULTI_CONSOLE_API=1.

The crash console doesn't use this API, it uses internally the core
functions of the 16550 console.

`bl31_plat_runtime_setup` is no longer needed. When this platform port
was introduced, that function used to disable the console. It was needed
to override that behaviour. The new behaviour is to switch to the
runtime console. The console is registered for all scopes (boot, crash
and runtime) in `rpi3_console_init` so it is not needed to override the
default behaviour anymore.

Update documentation.

This port can be compiled to boot an AArch64 or AArch32 payload with the
build option `RPI3_BL33_AARCH32`.

Note: This is not a secure port of the Trusted Firmware. This port is
only meant to be a reference implementation to experiment with an
inexpensive board in real hardware.
