ARM Versatile Express fixes for 3.15

This series contains straight-forward fixes for different
Versatile Express infrastructure drivers:

- NULL pointer dereference on the error path in the clk driver
- out of boundary array access in the dcscb driver
- broken restart/power off implementation
- mis-interpreted voltage unit in the spc driver

* tag 'vexpress/fixes-for-3.15' of git://git.linaro.org/people/pawel.moll/linux:
  ARM: vexpress/TC2: Convert OPP voltage to uV before storing
  power/reset: vexpress: Fix restart/power off operation
  arm/mach-vexpress: array accessed out of bounds
  clk: vexpress: NULL dereference on error path

Includes an update to 3.15-rc2
