[PATCH v3 3/4] ARM: dts: nxp: mxs: Adjust XEA board's DTS to support L2 switch

[Lukasz Majewski <lukma@denx.de>]

The description is similar to the one used with the new CPSW driver.

Signed-off-by: Lukasz Majewski <lukma@denx.de>
---
Changes for v2:
- Remove properties which are common for the imx28(7) SoC
- Use mdio properties to perform L2 switch reset (avoid using
  deprecated properties)

Changes for v3:
- Replace IRQ_TYPE_EDGE_FALLING with IRQ_TYPE_LEVEL_LOW
- Update comment regarding PHY interrupts s/AND/OR/g
