firmware/tegra: Enable Tegra186 BPMP support on Tegra194 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.

firmware: tegra: add bpmp driver for Tegra210 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.
