This patch makes the necessary changes to enable ARM platform to successfully integrate CryptoCell during Trusted Board Boot. The changes are as follows: * A new build option `ARM_CRYPTOCELL_INTEG` is introduced to select the CryptoCell crypto driver for Trusted Board boot. * The TrustZone filter settings for Non Secure DRAM is modified to allow CryptoCell to read this memory. This is required to authenticate BL33 which is loaded into the Non Secure DDR. * The CSS platforms are modified to use coherent stacks in BL1 and BL2 when CryptoCell crypto is selected. This is because CryptoCell makes use of DMA to transfer data and the CryptoCell SBROM library allocates buffers on the stack during signature/hash verification.
