Properties in kernel side

In order to ease the inclusion of vendor-specific properties,
properties are now mostly described in the kernel. This allows
a lower synchronization between user-side and kernel-side.

The only properties now handled at user-side are TA properties
(apart from "gpd.ta.appID") as well as the TEE property
"gpd.tee.arith.maxBigIntSize"

RPMB: add file encryption

Adds support for CFG_ENC_FS=y when CFG_RPMB_FS=y.

The files stored on an RPMB partition are encrypted with AES in Cipher
Block Chaining (CBC) mode with Encrypted Salt/Sector Initialization
Vector (ESSIV).
Each file has it own 128-bit File Encryption Key (FEK), randomly chosen
when the file is created. The FEK is added to the FAT entry for the
file, it is always decrypted with the Secure Storage Key (SSK) before
use. The file path is reduced accordingly, so that a FAT entry is still
256 bytes.
Each 256-byte block in the file is encrypted as follows:

k = 128 bits of SHA256(FEK);
IV = AES_Encrypt(k, block number);
encrypted_block = AES_CBC(IV, FEK, block_data);

core: stack unwinding

Adds support for stack unwinding, currently only done for fatal aborts
from kernel mode if CFG_CORE_UNWIND = y

The ARMv7/Aarch32 implementation uses -funwind-tables to generate frame
unwinding information which is quite large. Enabling stack unwinding
currently consumes ~8 KiB. The code to parse the frame unwind
information is imported from FreeBSD.

The Aarch64 implementation takes advantage of the frame pointer and has
minimal overhead. The core code to unwind the stack is imported from
FreeBSD.

Introduce CROSS_COMPILE32 and CROSS_COMPILE64

Currently, to build a 64-bit TEE core (as well as mixed 32- and 64-bit
TA libraries, which are automatically enabled in this case), one has to
set too many compiler variables:

$ make PLATFORM=hikey CFG_ARM64_core=y \
CROSS_COMPILE_core=aarch64-linux-gnu- \
CROSS_COMPILE_ta_arm64=aarch64-linux-gnu-

This commit introduces two variables, CROSS_COMPILE32 and
CROSS_COMPILE64. They take appropriate default values, so that the
above line may be simplified as:

$ make PLATFORM=hikey CFG_ARM64_core=y

The change remains compatible with previous builds, i.e., CROSS_COMPILE
can still be used to define the 32-bit compiler because CROSS_COMPILE32
defaults to $(CROSS_COMPILE). Similarly, CROSS_COMPILE_core and
CROSS_COMPILE_ta_arm{32,64} are still used so they may be overridden
too.
