From: Xiaowei Bao <xiaowei.bao@nxp.com>

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.
