ARM: dts: imx7d: Invert legacy PCI irq mapping

According to i.MX7D reference manual (Rev. 0.1, table 7-1, page 1221)
legacy PCI interrupt mapping is as follows:

 - PCIE INT A is IRQ 122
 - PCIE INT B is IRQ 123
 - PCIE INT C is IRQ 124
 - PCIE INT D is IRQ 125

Invert the mapping information in corresponding DT node to reflect
that.
