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.
