[PATCH v4 01/11] mfd: syscon: Add atmel-matrix registers definition

[Boris Brezillon]

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.

Changes since v3:
 - added AT91_MATRIX_USBPUCR_PUON definition
 - removed useless macros (those directly returning SoC specific register
   offsets)
