soc: qcom: mem-offline: Update end pfn calculation 



On a 6GB target with 0x80000000 as the base address, the
dram end address becomes 0x200000000. Now doing a phys_to_pfn
on this address gives a PFN which sits on this end address, which
is not a valid one. Hence, update the calculation of getting
the end PFN of the system.
