Usama Arif 1103d3b5a5 of/fdt: add dt_phys arg to early_init_dt_scan and early_init_dt_verify
[ Upstream commit b2473a359763e27567993e7d8f37de82f57a0829 ]

 __pa() is only intended to be used for linear map addresses and using
it for initial_boot_params which is in fixmap for arm64 will give an
incorrect value. Hence save the physical address when it is known at
boot time when calling early_init_dt_scan for arm64 and use it at kexec
time instead of converting the virtual address using __pa().

Note that arm64 doesn't need the FDT region reserved in the DT as the
kernel explicitly reserves the passed in FDT. Therefore, only a debug
warning is fixed with this change.
