First, improve the compatibility on newer Era CAAMs. These introduced new version registers. Secondly, add RNG support for the CAAM. This way we get random number generator support for EFI for free and KASLR will work with ARM64 kernels booted with bootefi.
Changes since v1: - instantiate RNG with prediction resistance - add annotation for caam_get_era() - fix all prints to match u-boots status lines - remove superfluous #ifdef CONFIG_DM_RNG - changed kconfig help text
