As part of Chain of Trust for Secure boot, the SPL U-Boot will validate the next level U-boot image. Add a new function spl_validate_uboot to perform the validation.
Enable hardware crypto operations in SPL using SEC block. In case of Secure Boot, PAMU is not bypassed. For allowing SEC block access to CPC configured as SRAM, configure PAMU.

Changes PATCH v5->PATCH v6: Incorporated review comments regarding comment style.
Changes PATCH v4->PATCH v5: Check for def CONFIG_SPL_DM and ndef CONFIG_SPL_FRAMEWORK instead of def CONFIG_DM macro to include call to dm_init_and_scan(). As dm_init_and_scan() is called as part of common SPL framework, so no need to call it again but in case of powerpc platforms which currently do not use common SPL framework, so need to include this function call here.
Changes PATCH v3->PATCH v4: Generic changes in lib, drivers, common Makefiles removed from this patchset. Rebased this patchset on top of patch [1], so this patchset is dependent on patch [1].
Changes PATCH v2->PATCH v3: Patches rebased
