[PATCH] it913x v1.23 use it913x_config.chip_ver to select firmware.

[PATCH] it913x v1.23 use it913x_config.chip_ver to select firmware.

[Malcolm Priestley]

As recommended by Jason at ITE, the chip version should select firmware.

However, to continue to support IT9137 firmware with different configuration
the driver will use udev->descriptor.idVendor to select the difference
between IT9135 and IT9137.
