Subject: [PATCH v4 2/5] ARM: bcm2835: add DT for the bcm2835 auxiliar devices

From: Martin Sperl <kernel@...tin.sperl.org>

Add device tree definitions for auxiliar bcm2835 devices:
* spi1
* spi2
* uart1

This also include a device to get used by the relevant
device-drivers (via a shared register) to enable/disable
the HW-block.
