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.

mlli_params.mlli_virt_addr is just a buffer of memory.
This allows to drop a cast.
No change in generated code.

crypto: ccree - protect against empty or NULL scatterlists2020-02-13T09:05:24+00:00Gilad Ben-Yossefgilad@benyossef.com2020-01-29T14:37:54+00:00urn:sha1:ce0fc6db38decf0d2919bfe783de6d6b76e421a9
Deal gracefully with a NULL or empty scatterlist which can happen
if both cryptlen and assoclen are zero and we're doing in-place
AEAD encryption.
This fixes a crash when this causes us to try and map a NULL page,
at least with some platforms / DMA mapping configs.

Replace internal cc_zero_sgl() with kernel API of the same function
sg_zero_buffer().

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.
