scripts: objdiff: get the path to .tmp_objdiff more simply

This commit is a minor refactoring.

Temporary files for objdiff are stored in .tmp_objdiff directory
which is located at the top directory.

To get the path to this directory,

  SRCTREE=`git rev-parse --show-toplevel`
  TMPD=$SRCTREE/.tmp_objdiff

seems easier to understand than

  GIT_DIR=`git rev-parse --git-dir`
  TMPD=${GIT_DIR%git}tmp_objdiff

Besides, it is not always necessary to create .tmp_objdiff dicrectory.
It should be created only for "record" command.

boards.cfg: fix a configuration error of ep8248 board again

"make ep8248_config" fails with an error like this:

    $ make ep8248_config
    make: *** [ep8248_config] Error 1

Its cause is that there are two entries for "ep8248".

The first is around line 661 of boards.cfg. (as Active)
The second appears around line 1242. (as Orphan)

This bug was originally introduced by commit e7e90901
and I fixed it by commit 8ad5d45e.
(Refer to git-log of commit 8ad5d45e)

But this bug was re-introduced by commit 05d134b0 because
the custodian made a mistake when he resolved a merge conflict.

arm: fix a build error with CONFIG_USE_IRQ

Commit 41623c91 moved exception handling to arch/arm/lib/vectors.S,
breaking CONFIG_USE_IRQ feature.

If CONFIG_USE_IRQ is enabled, undefined reference error occurs.

  arch/arm/lib/built-in.o: In function `interrupt_init':
  arch/arm/lib/interrupts.c:37: undefined reference to `IRQ_STACK_START'
  arch/arm/lib/interrupts.c:37: undefined reference to `FIQ_STACK_START'
  make: *** [u-boot] Error 1

Because arch/arm/lib/vectors.S includes references to
CONFIG_SYS_DV_NOR_BOOT_CFG and CONFIG_USE_IRQ, it must include <config.h>.

arm: fix a double-definition error of _start symbol

The symbol "_start" is defined twice in arch/arm/lib/vectors.S:
around line 48 and line 54.

If CONFIG_SYS_DV_NOR_BOOT_CFG is defined (as on calimain board),
build fails:

  arch/arm/lib/vectors.S: Assembler messages:
  arch/arm/lib/vectors.S:54: Error: symbol `_start' is already defined
  make[1]: *** [arch/arm/lib/vectors.o] Error 1

objdiff: change the extension of disassembly from .o to .dis

Prior to this commit, the command "scripts/objdiff record path/to/*.o"
disassembles the given object into ".tmp_objdiff/path/to/*.o" file.

The problem here is that recorded disassemblies are lost if we run
"make clean" because "make clean" removes all the *.o files.
Disassembled code should be dumped into rather *.dis file.

zynq: disable -Wstrict-prototypes option for ps7_init.c

The files ps7_init.c and ps7_init.h are supposed to be generated by
hw projects such as Vivado, PlanAhead and then to be copied into
board/xilinx/zynq directory.

But some prototypes in them cause annoying warning messages:

  CC      spl/board/xilinx/zynq/ps7_init.o
In file included from board/xilinx/zynq/ps7_init.c:50:0:

board/xilinx/zynq/ps7_init.c:12854:6: warning: function declaration isn't a prototype [-Wstrict-prototypes]

The prototypes should be

  int ps7_init(void);
  int ps7_post_config(void);
  int ps7_debug(void);

rather than

  int ps7_init();
  int ps7_post_config();
  int ps7_debug();

We do not want to be bothered because of automatically generated files.
But we cannot touch the external projects for now.
What we can do is to disable -Wstrict-prototypes for ps7_init.c
