[PATCH 01/12] mfd: syscon: Add atmel-matrix registers definition

[Alexandre Belloni]

From: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx>

AT91 SoCs have a memory range reserved for internal bus configuration.
Expose those registers so that drivers can make use of the matrix syscon
declared in at91 DTs.
