timestamp: Remove HAS_PRECBMEM_TIMESTAMP_REGION Kconfig

This patch generalizes the approach previously used for ARM32
    TTB_SUBTABLES to "auto-detect" whether a certain region was defined in
    memlayout.ld. This allows us to get rid of the explicit Kconfig for the
    TIMESTAMP region, reducing configuration redundancy and avoiding
    confusion when setting up future boards.

(Removing armv4/bootblock_simple.c because it references this Kconfig
    and it is a dead file that I just forgot to remove in CL:12076.)

BRANCH=None
    BUG=None
    TEST=Booted Oak and confirmed that all pre-RAM timestamps are still
    there. Built Nyan and Falco.
