[PATCH v1] spmi: msm: Fix V5 ownership table offset

[Aswin Murugan]

The driver reads ownership registers from the wrong address for V5.
The ownership table is at offset 0x700 from spmi_cnfg base, not 0x0.
This causes incorrect peripheral ownership detection and potential
access violations.

Add the missing 0x700 offset to match the kernel driver [1]
