layerscape: add ls1088ardb device support

Browse Source 
LS1088A is an ARMv8 implementation combining eight ARM A53 processor
cores. The LS1088ARDB is an evaluatoin platform that supports the
LS1088A family SoCs.

Features summary:
- Eight 64-bit ARM v8 Cortex-A53 CPUs
- Data path acceleration architecture 2.0 (DPAA2)
- Ethernet interfaces
- QUADSPI flash, 3 PCIe, 2 USB, 1 SD, 2 DUARTs etc

Subject: [PATCH 216/226] dpaa2-evb: Fix interrupt handling
Mask only the events handled by the driver - DPDMUX_IRQ_EVENT_LINK_CHANGED.
Use clear-on-read mechanism for the interrupt status and avoid calling
dpdmux_clear_irq_status(). Status contains the events handled (only link
state change for the moment) and masks the first 16-bits, as they are used
to store the interface ID that generated the event.
