Subject: [PATCH 5/6] nvmem: qcom-spmi-sdam: Set size in struct nvmem_config

From: Luca Weiss <luca.weiss@...rphone.com>

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  |................|
