Before this patch the checks of the parameters buffers for a TA where
required to be physical pointers. When a static TA is invoked from a
user TA the virtual addresses of the buffers aren't translated to
physical addresses as they will be translated back to the same virtual
address again. With this patch the parameters buffers are tagged as
containing virtual addresses allowing the checks to take that into
account.

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);
