There are currently no in-tree users of the Qualcomm SDAM nvmem driver
and there is generally no point in registering a driver that can be
built as a module at subsys init time.
Register the driver at the normal device init time instead and let
driver core sort out the probe order.

Add the missing module device table so that the driver can be autoloaded
when built as a module.

"sdam->pdev" is uninitialized and it is used to print error logs.
Fix it. Since device pointer can be used from sdam_config, use it
directly thereby removing pdev pointer.

Using pdev->id as the nvmem's config ID (which, by default, is
NVMEM_DEVID_NONE) prevents multiple instances of this driver from
probing because of the following error:
sysfs: cannot create duplicate filename '/bus/nvmem/devices/spmi_sdam'
Use NVMEM_DEVID_AUTO as the NVMEM config ID to fix the issue.

QTI SDAM driver allows PMIC peripherals to access the shared memory
that is available on QTI PMICs.
Use subsys_initcall as PMIC SDAM NV memory is accessed by multiple PMIC
drivers (charger, fuel gauge) to store/restore data across reboots
required during their initialization.
