Optimize mmu handling

Previously there was two complete L1 mmu tables where one was only
used when kernel mapping was active and the other when user mapping
was active too. In addition to that there was several sets of L2 mmu
tables which where unused.

Now there's only one complete L1 mmu table shared by all CPUs. There's
one small L1 mmu table for each thread used to keep user mappings. The
small L1 mmu tables takes each 128 bytes and can spans 32 MiB of
virtual memory.

This change saves memory ~32 KiB, but also prepares for multiprocessing
since each thread has its own user mapping.

Due to the change of mmu table handling many low level assembly and C
functions are changed, and some even removed.

Implemented wait in normal world

Instead of busy waiting in secure world, it is more efficient to wait
in normal world such that HLOS can schedule another task to execute
while waiting

- Added a new RPC command to wait in linux driver
- Remove wait_specific() hook in time_source, it seems can be a generic
function.
- This patch depends on "Implemented wait in normal world" in
optee_linuxdrver

Reentrancy fixes

Before this patch: The normal world was only allowed to enter
secure world with one thread at a time.

After this patch: The normal world may try to enter secure world
with as many threads as it likes, secure world will return busy
when no more threads can be allowed. Secure world still only allows
one active thread at a time, but during RPC another thread may enter
and do some work. This is needed for cancellation to work.

* Adds a mutex that waits in normal world if busy
* Adds a new RPC service to wait in normal world
* Imports bitstring.h from FreeBSD to aid mutex implementation
* Adds a critical section in tee_ta_init_session
* Unmaps TA before RPC exit and maps it again on return to handle
rescheduling of threads during RPC
* Doesn't clear a1-a3 when returning busy
* Bugfixes vector_std_smc_entry

This patch depends on the "Allow parallel entries to secure world"
patch in optee_linuxdriver.

* A TA is only loaded via tee-supplicant, directly supplying a

This requires and update to the client lib to avoid leaking

* Divides tee_ta_load() into several functions with one

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
