[PATCH v2 2/2] ARM: i.MX53: dts: add support for MCIMX53-START-R

[Steffen Trumtrar <s.trumtrar@pengutronix.de>]

The start-r QSB has a different pmic than the older start QSB.
Add a new dts for the QSRB and let barebox generate two images when
LOCO is selected.

Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de>

Changes in V2:

	- add newlines after every DT-node
	- add phandle names to pmic-nodes
