ARM: Generalize armv7 as arm.

There are ARM systems which are essentially heterogeneous multicores where
    some cores implement a different ARM architecture version than other cores. A
    specific example is the tegra124 which boots on an ARMv4 coprocessor while
    most code, including most of the firmware, runs on the main ARMv7 core. To
    support SOCs like this, the plan is to generalize the ARM architecture so that
    all versions are available, and an SOC/CPU can then select what architecture
    variant should be used for each component of the firmware; bootblock,
    romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.

We don't always want to use ARMv7 code when building for ARM, so we should
    separate out the ARMv7 code so it can be excluded, and also make it possible
    to include code for some other version of the architecture instead, all per
    build component for cases where we need more than one architecture version
    at a time.

The tegra124 bootblock will ultimately need to be ARMv4, but until we have
    some ARMv4 code to switch over to we can leave it set to ARMv7.

Squashed two related patches for splitting ARM support into general
    ARM support and ARMv7 specific pieces.
