This patch set adds a SPI-NOR driver for stm32 QSPI controller.

The quadspi is a specialized communication interface targeting single,
dual or quad SPI Flash memories.
It can operate in any of the following modes:
-indirect mode: all the operations are performed using the quadspi
registers
-read memory-mapped mode: the external Flash mem
This fixes a math error calculating the extra_vecs. The error assumed
only 1 cpu per vector, but the value needs to account for the actual
number of cpus per vector in order to get the correct remainder for
extra CPU assignment.

clang currently does not support these optimizations, only enable them

In order to use "len" to check for xenbus_read errors properly, we need
to initialize len to 0 before passing it to xenbus_read.

When we are propagating voltage changes to parent regulators don't
bother if the parent does not have permission to change voltages. This
simplifies error checking in the function for cases where the regulator
lacks some of the voltage operations.

Rather than just not resolving the supply when there is explicitly no
supply mapping fall through and allow a dummy supply to be substituted.
