[PATCH] nvmem: qcom-spmi-sdam: Set size in struct nvmem_config

[Luca Weiss]

Let the nvmem core know what size the SDAM is, most notably this fixes
the size of /sys/bus/nvmem/devices/spmi_sdam*/nvmem being '0' and makes
user space work with that file.
  ~ # hexdump -C -s 64 /sys/bus/nvmem/devices/spmi_sdam2/nvmem
  00000040  02 01 00 00 04 00 00 00  00 00 00 00 00 00 00 00  |................|
  00000050  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|

Related, it would be nice to set sdam->sdam_config.type to an
appropriate value, the ones currently upstream are:

  enum nvmem_type {
      NVMEM_TYPE_UNKNOWN = 0,
      NVMEM_TYPE_EEPROM,
      NVMEM_TYPE_OTP,
      NVMEM_TYPE_BATTERY_BACKED,
      NVMEM_TYPE_FRAM,
  };

I don't know what would fit for SDAM and I couldn't find any info on
createpoint either, not even what the abbreviation SDAM stands for.
