5.10-stable review patch. If anyone has any objections, please let me know.

commit e88f516ea417c71bb3702603ac6af9e95338cfa6 upstream.
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.
