This patchset adds SoC info driver which can provide information
such as Chip ID, Chip family and serial number about Qualcomm SoCs
to user space via sysfs. Furthermore, it allows userspace to get
information about custom attributes and various image version
information via debugfs.
The patchset cleanly applies on top of v5.0-rc6.
Changes since v1:
- Align ifdefs to left, remove unnecessary debugfs dir
creation check and fix function signatures in patch 3
- Fix comment for teh case when serial number is not
available in patch 1
Changes since v2:
- Reorder patches [patch five -> patch two]
Changes since v3:
- Add reviewed-bys from Greg
- Fix build warning when debugfs is disabled
- Remove extra checks for dir creations in patch 5
