firmware: tegra: bpmp: Add tegra_bpmp_get_with_id() function
Some device tree bindings need to specify a parameter along with a BPMP
phandle reference to designate the ID associated with a given controller
that needs to interoperate with BPMP. Typically this is specified as an
extra cell in the nvidia,bpmp property, so add a helper to parse this ID
while resolving the phandle reference.
