Enable support for the BPMP on Tegra234 to avoid relying on Tegra194 being enabled to pull in the needed OF device ID table entry. On simulation platforms the BPMP hasn't booted up yet by the time we probe the BPMP driver and the BPMP hasn't had a chance to mark the doorbell as ringable by the CCPLEX. This corresponding check in the BPMP driver will therefore fail. Work around this by disabling the check on simulation platforms. Reviewed-by:

This function extracts the PRE_SI_PLATFORM field from the HIDREV register and can be used to determine which platform the kernel runs on (silicon, simulation, ...). Note that while only Tegra194 and later define this field, it should be safe to call this on prior generations as well since this field should read as 0, indicating silicon. Reviewed-by:
