core: import GHASH acceleration routines

Imports assembly code for accelerated GHASH computations and provides an
interface for using these low level functions.

The assembly code relies on features now available in all ARM cores. No
assembly code is enabled at all unless CFG_CRYPTO_WITH_CE = y. Code
using the PMULL/PMULL2 instruction is enabled with CFG_HWSUPP_PMULL = y.

The assembly code is written by Ard Biesheuvel
<ard.biesheuvel@linaro.org> and modified slightly here to fit better
into OP-TEE.

core: extend mutex to support read locks

Extends mutex implementation to support read locks in addition to the
default lock which has write lock semantics.

With read locks multiple threads can simultaneously acquire a read lock,
typically used for read only access to a shared resource.

The default mutex_lock behaves as a write lock with only a single thread
at a time able to acquire the write lock, typically used for exclusive
access to a shared resource.

core: pager can use memory between SRAM start and core load address

If core is loaded some 4kB pages above the start of the physical
internal ram, some 4kB memory block will not be used by the pager.

This situation can occur if the beginning of the internal ram is
used by a bootloader. Bootloader must load op-tee above its own
used memory. Such bootloader memory is freely available to op-tee
core (pager).

This change adds the physical memory between TEE RAM base address
and the op-tee entry point address to the pager page pool. This
change also default maps this area so that pager identifies physical
pages as valid page addresses.

This changes fixes the plat-vexpress against CFG_TEE_RAM_START being
different from CFG_TEE_LOAD_ADDR.
