remoteproc: qcom: pas: Adjust the phys addr wrt the mem region
The minidump table in the toc contains physical addresses that may lie
before the physical address of the first elf segment in relocatable
images. This change adds a custom dump function for minidumps which
calculates the offset into the carveout region using the start of
the physical address instead of the start of the first elf segment.
