You may not need to patch this in at all. I think the PBIAS is there
only for the first slot and it's hardwired so it's always there. If
that's the case, then you can just always request it. Or use the
compatible flag if needed.

pbias is not applicable for mmc1 on am33xx and is applicable for
only for OMAP2-OMAP5, so I can add pbias-supply to omapx.dtsi files
