nvmem: qcom-spmi-sdam: Migrate to devm_spmi_subdevice_alloc_and_add()

Some Qualcomm PMICs integrate a SDAM device, internally located in
a specific address range reachable through SPMI communication.

Instead of using the parent SPMI device (the main PMIC) as a kind
of syscon in this driver, register a new SPMI sub-device for SDAM
and initialize its own regmap with this sub-device's specific base
address, retrieved from the devicetree.

This allows to stop manually adding the register base address to
every R/W call in this driver, as this can be, and is now, handled
by the regmap API instead.
