armv8: ls1043ardb: invert irq pin polarity for AQR105 PHY
To use AQR105 PHY's interrupt, we need to invert the IRQ pin polarity by setting relative bit in SCFG_INTPCR register, because AQR105 interrupt is low active but GIC accepts high active. Signed-off-by: Shaohui Xie <Shaohui.Xie@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
