arm64: Prepare ARM64 for building

There were a number of issues with the ARM64 build files. This
patch ports the following changes from ARMV4/V7 to ARMV8:

  - make armv8 Kconfig options consistent with armv4/v7
  - fix build include issues in boot.c, tables.c,
    and early_variables.h by matching armv4/v7.
