drm/i915/psr: Try to program link training times correctly The default of 0 is 500us of link training, but that's not enough for some platforms. Decoding this correctly means we're using 2.5ms of link training on these platforms, which fixes flickering issues associated with enabling PSR. v2: Unbotch the math a bit. v3: Drop debug hunk. v4: Improve commit message.
