Subject: [Patch v3 0/6] GSBI CRCI Autoconfiguration Support

This patch set adds support for automatic configuration of GSBI DMA CRCI values.

DMA operations require that the ADM CRCI mux values be properly configured in
the TCSR (Top Control and Status Register) block.  During probing of a GSBI
device, the client mode must be declared and this can be used to lookup the
correct TCSR ADM CRCI MUX settings and then program them so that they are
correct before any clients are populated.

These patches add the TCSR as a syscon device and that allows the GSBI to
access and manipulate the ADM CRCI MUX registers to correctly configure the
values based on the GSBI port configuration.

Changes since v2:
  - Use cell-index instead of alias to denote GSBI instance

Changes since v1:
  - Fixed various review comments
