Subject: [PATCH v2 4/4] BSC9131rdb/dts: Add nodes for supporting AIC

From: Akhil Goyal <akhil.goyal@...escale.com>

BSC9131 is a hetrogenous system where Antenna interface controller
(AIC) is a part of DSP subsystem. But its configuration is done from
PA side. So a DSP node is added with appropriate CCSR address visible
to PA and hence the address space for AIC will be visible to PA.

BSC9131 support 3 AIC lanes for ADI interface and 3 for MAXIM type of
interface. This patch support only ADI lanes.
