[U-Boot] [PATCH] armv8: ls1043ardb: invert irq pin polarity for AQR105 PHY

From: Shaohui Xie Shaohui.Xie@nxp.com
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.

Applied to u-boot-fsl-qoriq master, awaiting upstream.
Thanks.
