Subject: [PATCH 2/2] nvmem: qcom-spmi-sdam: Fix uninitialized pdev pointer

From: Subbaraman Narayanamurthy <subbaram@...eaurora.org>

"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.

Fixes: 40ce9798794f ("nvmem: add QTI SDAM driver")
