coreboot arm64: Add support for arm64 into coreboot framework

Add support for enabling different coreboot stages (bootblock, romstage and
    ramstage) to have arm64 architecture. Most of the files have been copied over
    from arm/ or arm64-generic work.

This patch is essentially a squash of aarch64 changes made by
    these patches:

d955885 coreboot: Rename coreboot_ram stage to ramstage
    a492761 cbmem console: Locate the preram console with a symbol instead of a sect
    96e7f0e aarch64: Enable early icache and migrate SCTLR from EL3
    3f854dc aarch64: Pass coreboot table in jmp_to_elf_entry
    ab3ecaf aarch64/foundation-armv8: Set up RAM area and enter ramstage
    25fd2e9 aarch64: Remove CAR definitions from early_variables.h
    65bf77d aarch64/foundation-armv8: Enable DYNAMIC_CBMEM
    9484873 aarch64: Change default exception level to EL2
    7a152c3 aarch64: Fix formatting of exception registers dump
    6946464 aarch64: Implement basic exception handling
    c732a9d aarch64/foundation-armv8: Basic bootblock implementation
    3bc412c aarch64: Comment out some parts of code to allow build
    ab5be71 Add initial aarch64 support

The ramstage support is the only portion that has been tested
    on actual hardware. Bootblock and romstage support may require
    modifications to run on hardware.
