libpayload: Make the region to scan for the cb tables configurable.

The address range to scan for the coreboot tables varies from machine to
    machine based on the range memory occupies on the SOC being booted and on the
    amount of memory installed on the machine. To make libpayload work on
    different ARM systems with different needs, this change makes the region to
    scan configurable. In the future, we might want to come up with a more
    automatic mechanism like on x86, although there's less consistency on ARM as
    far as what ranges are even memory in the first place.
