The MC34708 PMIC interrupt level is active high, but was set to
active low in the devicetree, probably as a result of a copy and
paste error from the QSB board.
This caused IRQ storms and led to the kernel disabling the PMIC
interrupt.

Both imx53-qsb and imx53-qsrb don't have external pull-up resistors
on the I2C1 SCL and SDA lines populated. Select open-drain mode and
enable the internal pull-up for both.

The "Start-R QSB" has a different PMIC than the older "Start QSB".
Add a new devicetree for the Start-R.
They both could use the same DT, as both PMICs (the dialog and the mc34708)
have different i2c addresses and could coexist in the same DT without any
errors. But once phandles are used, this will get messy.
The pmic nodes are based on an earlier patch
[PATCH] arm: imx53-qsb: Add Ripley driver DT nodes
from
Ying-Chun Liu (PaulLiu) <paul.liu@linaro.org>
which apparently got lost/abandoned.
I added phandles/newlines and changed the node name from ripley to mc34708.
