Changes in v10: 1. Sort the order in Kconfig and Makefile. Changes in v9: 1. Check if the return value is -ENOMEM when reading efuse data fails. Changes in v8: 1. Use "device_property_present()" to increase human readability; 2. Use "GPL" as recommended in commit bf7fbeeae6db ("module: Cure the MODULE_LICENSE "GPL" vs. "GPL v2" bogosity"). Changes in v7: 1. Add bitfield.h header to fix the build error on non-arm64 platforms. Changes in v6: 1. Remove unnecessary header files; 2. Use FILELD_PREP in bitfield.h to set value. Changes in v5: 1. Fix typo in kerneldoc: "eFues" => "eFuse". Changes in v4: 1. Fix no return when calling dev_err_probe. Changes in v3: 1. Add introductions for structure members; 2. Add SoC dependent data; 3. Dynamically allocate efuse data; 4. Check return value if it's an -EPROBE_DEFER. Changes in v2: 1. Add specific compatible name; 2. Read NVMEM data at probe time; 3. Fix typos.
