npu2-opencapi: Fix 'link internal error' FIR, take 1
npu2-opencapi: Fix 'link internal error' FIR, take 1

When we setup a link, we always enable ODL0 and ODL1 at the same time
in the PHY training config register, even though we are setting up
only one OTL/ODL, so it raises a "link internal error" FIR bit in the
PowerBus OLL FIR Register for the second link. The error is harmless,
as we'll eventually setup the second link, but there's no reason to
raise that FIR bit.

The fix is simply to only enable the ODL we are using for the link.
