Add CFG_PGT_CACHE_ENTRIES to allow platforms to customize the page
table cache size. This is needed for example when a platform is to
support very large TAs of several dozen of Mbytes of private memory
(code/data).

Move PGT_CACHE_SIZE macro definition from pgt_cache.h to pgt_cache.c
since it is used only in that source file.

By the way, fix pgt_cache.h layout to have header files includes first
followed by macro definitions.

OP-TEE currently doesn't support using a different hash for MGF1
with RSA-OAEP. However, this is required for AOSP compatibility
(e.g. in EncryptionOperationsTest.RsaOaepWithMGFDigestSuccess [1]).

Pass the MGF1 attribute to crypto implementations. Note that
only libtomcrypt supports this feature at the moment, so other
implementations will either fail or fall back to libtomcrypt when
passed a different MGF1 hash.

core: fix race condition on TA/PTA/StMM context loading

Fix race condition on creation of a context for single instance TAs,
PTAs or StMM application. Such race condition could occur and lead to
duplicated contexts if connected close enough that they are created
after tee_ta_init_session() calls tee_ta_init_session_with_context()
and before the context are added in the centralized context list.

This is realized by keeping tee_ta_mutex held while tee_ctxes list is
looked up for matching a context or a new context is added into that
list with its .is_initializing field activated. For that purpose
user TA and StMM application initialization function are split in
2 functions, the 2nd one used to finalizes the context creation
started in the 1st function.

By the way, add inline description comments and fix indentation issues
in uaer_ta.h and remove the inline comment in pseudo_ta.c that refers
to TA loading whereas the function relates to PTA contexts creation.

core: firewall: add firewall framework

Add a generic firewall controller framework. The goal of this framework
is to offer access control and configuration APIs, that are implemented
in the firewall controllers drivers, to the firewall consumers. This
framework requires an embedded device tree.

A firewall controller is an access controller [1]. It should register
itself as a provider to the framework. Firewall controllers have the
possibility to populate their bus according to defined firewall accesses
defined in the "access-controllers" property in each of the device's
node.

Any device that consumes one or more firewall should refer it/them in
their "access-controllers" property. Arguments can be passed along with
the phandle of the firewall controller(s).
