ARM: dts: imx53-ppd: Fix ACHC entry 



[ Upstream commit cd7cd5b716d594e27a933c12f026d4f2426d7bf4 ]

PPD has only one ACHC device, which effectively is a Kinetis
microcontroller. It has one SPI interface used for normal
communication. Additionally it's possible to flash the device
firmware using NXP's EzPort protocol by correctly driving a
second chip select pin and the device reset pin.
