The BPMP implementation on Tegra194 is mostly compatible with the
implementation on Tegra186, so make sure the latter is available when
support for Tegra194 is enabled.

Only include support for Tegra210 and Tegra186 in the BPMP driver if
support for those SoCs was selected. This fixes a build failure seen
on 32-bit ARM allmodconfig builds, but could also happen on 64-bit
ARM builds if either Tegra210 or Tegra186 were not selected.

This patch adds driver for Tegra210 BPMP firmware.
The BPMP is a specific processor in Tegra210 chip, which runs firmware
for assisting in entering deep low power states (suspend to ram), and
offloading DRAM memory clock scaling on some platforms.

Split BPMP driver into common and chip specific parts to facilitate
adding support for previous and future Tegra chips that are using BPMP
as co-processor.
