Suppress error message when nvgpu tries to load VBIOS overlay, but
one is not found. This situation is normal. This is done by moving
gk20a_request_firmware() to be nvgpu generic function
nvgpu_request_firmware(), and adding a NO_WARN flag to it.
Introduce also a NO_SOC flag to suppress attempt to load firmware
from SoC specific directory in addition to the chip specific
directory. Use it for dGPU firmware files.
