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.

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.
