arm64: defconfig: enable Qualcomm SDAM nvmem driver

The SDAM nvmem driver can be used to access the Shared Direct Access
Memory Module registers in some Qualcomm PMICs.

These registers can specifically be used to store a time offset on
platforms where the PMIC RTC time registers are read-only in order to
allow the RTC time to be updated.
