SRAM addresses are small integer offsets into local SRAM. Currently
they are stored using a mixture of cc_sram_addr_t (u64), u32, and
dma_addr_t types.
Settle on u32, and remove the cc_sram_addr_t typedefs.
This allows to drop several casts.

Use the existing lower_32_bits() and upper_32_bits() macros instead of
explicit casts and shifts to split a 64-bit address in its two 32-bit
parts.
Drop the superfluous cast to "u16", as the FIELD_PREP() macro already
masks it to the specified field width.

encapsulate set_cipher_mode call with another api,
preparation for specific hash behavior as needed in later patches
when SM3 introduced.

Clang warns when one enumerated type is implicitly converted to another
and this happens in several locations in this driver, ultimately related
to the set_cipher_{mode,config0} functions. set_cipher_mode expects a mode
of type drv_cipher_mode and set_cipher_config0 expects a mode of type
drv_crypto_direction.
drivers/crypto/ccree/cc_ivgen.c:58:35: warning: implicit conversion from
enumeration type 'enum cc_desc_direction' to different enumeration type
'enum drv_crypto_direction' [-Wenum-conversion]
set_cipher_config0(&iv_seq[idx], DESC_DIRECTION_ENCRYPT_ENCRYPT);
drivers/crypto/ccree/cc_hash.c:99:28: warning: implicit conversion from
enumeration type 'enum cc_hash_conf_pad' to different enumeration type
'enum drv_crypto_direction' [-Wenum-conversion]
set_cipher_config0(desc, HASH_DIGEST_RESULT_LITTLE_ENDIAN);
drivers/crypto/ccree/cc_aead.c:1643:30: warning: implicit conversion
from enumeration type 'enum drv_hash_hw_mode' to different enumeration
type 'enum drv_cipher_mode' [-Wenum-conversion]
set_cipher_mode(&desc[idx], DRV_HASH_HW_GHASH);
Since this fundamentally isn't a problem because these values just
represent simple integers for a shift operation, make it clear to Clang
that this is okay by making the mode parameter in both functions an int.

Introduce basic low level Arm TrustZone CryptoCell HW support.
This first patch doesn't actually register any Crypto API
transformations, these will follow up in the next patch.
This first revision supports the CC 712 REE component.
