[PATCH v2 1/9] PCI: microchip: Correct the DED and SEC interrupt bit offsets

From: Daire McNamara <daire.mcnamara at microchip.com>

The SEC and DED interrupt bits were the wrong way round so the SEC
interrupt handler attempted to mask, unmask, and clear the DED interrupt
and vice versa. Correct the bit offsets so each interrupt handler
operates properly.

Fixes: 6f15a9c9f941 ("PCI: microchip: Add Microchip PolarFire PCIe controller driver")
