At several occasions it would be useful to dump the fdt
blob being passed to the second (kexec/kdump) kernel
when '-d' flag is specified while invoking kexec/kdump.
This allows one to look at the device-tree fields that
is being passed to the secondary kernel and accordingly
debug issues.
This ca
Since during the arm64 kexec_load()/kdump invocation,
the dtb is passed to the second kernel, it is sometimes useful
to dump the dtb contents (to verify the correctness
of the same).
This patch adds this feature which is enabled when '-d' flag is
used with kexec command line invocation.

~ Removing usage of local pointer variable in 'dump_fdt()' function.
~ Tried addressing a comment regarding converting GET_CELL macro to
inline function,
