Writing to Device Registers: nbcsWrite
This function is used to write to a register of a specific Narrowband Chipset device by providing
the register number. This function derives the actual address location based on the device handle
and register number inputs. It then writes the contents of this address location to the device. Note
that a failure to write returns a zero and that any error indication is written to the CSDDB.
