firmware: tegra: Propagate error code to caller
Response messages from Tegra BPMP firmware contain an error return code as the first word of payload. The error code is used to indicate incorrectly formatted request message or use of non-existing resource (clk, reset, powergate) identifier. Current implementation of tegra_bpmp_transfer() ignores this code and does not pass it to caller. Fix this by adding an extra struct member to tegra_bpmp_message and populate that with return code.
