sb/intel/bd82x6x/early_usb: Add USB TX/RX gains
Describe the USB 'current' settings based on MRC.bin that converts
the USB trace length to a predefined register value.
MRC.bin decides which setting to use based on the PC type, mobile
or desktop, and the trace length.
Tested: Lenovo X220 still boots.
