From: Xiaowei Bao <redacted> Due to the INTA is shared with the active-low PHY2 interrupt on P1010RDB-PA board, so configure P1010RDB-PA's INTA with polarity as active-low, the P1010RDB-PB board is used separately, so configure P1010RDB-PB's INTA with polarity as active-high. The INTX in P1010RDB-PB do not work because of the pcie@0 node fixup will be overwrited by p1010si-post.dtsi file, so we move the pcie@0 node fixup to p1010rdb-pb.dts and p1010rdb-pb_36b.dts.
