Get value of gpd.tee.arith.maxBigIntSize from libutee

The property gpd.tee.arith.maxBigIntSize was implemented in TEE core by
tee_svc_sys_get_property() which was returning a constant taken from the
crypto module (LTC_MAX_BITS_PER_VARIABLE / 2).
The correct value is TEE_MAX_NUMBER_OF_SUPPORTED_BITS from libutee.
This commit makes libutee return the appropriate value directly (without
calling the TEE core) and deletes the property from the syscall.
Additionally, this removes the unjustified dependency of tee_svc.c on
<tee_ltc_wrapper.h>.

mk/compile.mk: simplify dependency generation; better support ccache

This commit modifies the compilation flags that are used to generate
dependency files (*.o.d). Rather than using the preprocessor's -MD flag
(-Wp,-MD,<depfile>), we now use the frontend's equivalent (-MD -MF <depfile>
-MT <target>).

There are three reasons for doing so:
1. The GCC man page recommends against using -Wp, because "the
preprocessor's direct interface is undocumented and subject to change".
2. The new flags generate the correct rule directly, including the
subdirectory in front of the object name, so scripts/fixdep is not needed
anymore.
3. ccache (3.1.9) would not handle -Wp,-MD as expected. It would preserve
the directory prefix, so that we would end up with an invalid path after
the fixdep phase, making the rules useless. With this patch, OP-TEE builds
fine with ccache:
make -j3 CROSS_COMPILE="ccache arm-linux-gnueabihf-"

Cleanup loading/unloading of a TA

* A TA is only loaded via tee-supplicant, directly supplying a
pointer to the TA binary is not supported any longer.
This requires and update to the client lib to avoid leaking
shared memory.
* The shared memory used to load the TA is freed as soon as the
TA have been loaded into secure memory
* Divides tee_ta_init_session() into sevaral functions
* Divides tee_ta_close_session() into two functions
* Divides tee_ta_load() into several functions with one
separate function for signature verification
* Removes some unused code for kernel TAs
* Removes the option to lock/unlock a TA is only used by kernel
TAs which we don't support any longer.
* Removes the static global tee_rs. Switch to use Thread Local
Storage pointer provided by the thread handler.
* Adds TA_FLAG_USER_MODE by default to TA header since
all TAs are user mode TAs now.
* Reformats user_ta_header.c to make checkpatch less unhappy with it.

Add plat-vexpress

* Initial support for Versatile Express of FVP with ARM Trusted
Firmware (ATF below)

* Use entry vector for entering TEE

Align interface between TEE and secure monitor with the interface
between OPTEED in ATF and TEE.

Uses an ATF compatible entry vector for entering TEE from internal
secure monitor.

Internal secure monitor saves entry reason to be able to tell when
switching back to nonsecure world if r0-r3 should be preserved (FIQ case)
or returned as is (normal call case).

* Many small fixes of generic problems that could affect other platforms
too.

* Disable unaligned data accesses by adding compiler flag
-mno-unaligned-access

* Adds support for Versatile Express of QEMU with 8 MiB of secure DRAM
