 * Add dt-bindings for secure qfprom
 * Refactor LLCC driver to support multiple configuration
 * Add support for multi channel DDR configuration in LLCC
 * Add LLCC support for the Qualcomm QDU1000 and QRU1000 SoCs

Changes in v4 -
 - Created a separate driver for reading from secure fuse region as suggested.
 - Added patch for dt-bindings of secure qfprom driver accordingly.
 - Added new properties in the dt-bindings for LLCC. 
 - Implemented new logic to read the nvmem cell as suggested by Bjorn.
 - Separating the DT patches from this series as per suggestion.

Changes in v3-

The patches in this series are going to be merged by two different
maintainers, the interface between them is an existing, clean API, so it
will be possible to merge the two halfs independently.

So please split this into one series for the addition of the nvmem
driver and one for the llcc pieces (with the nvmem interface/stub update
in the llcc one).

Thanks,
Bjorn
