IMX: Rename IMX image "SPL" to something else for Cygwin

I am not sure how much effort we should make
for building U-Boot on Cygwin.

Anyway, other than host programs, I notice file name problem.

Unlike Unix or Linux, on Windows upper/lower cases for file names
are not distinguished.

On Cygwin, for example, we cannot do this:

  $ mkdir abc
  $ mkdir ABC
  mkdir: cannot create directory `ABC': File exists

It causes some problems in U-Boot too.

For example,

  $ make mrproper
    CLEAN   SPL
  rm: cannot remove `SPL': Is a directory
  Makefile:1278: recipe for target 'clobber' failed
  make: *** [clobber] Error 1

  $ make qong_config
  Configuring for qong board...

  $ make clean
    CLEAN   arch/arm/imx-common
  rm: cannot remove `arch/arm/imx-common/../../../SPL': Is a directory
  scripts/Makefile.clean:79: recipe for target '__clean' failed
  make[1]: *** [__clean] Error 1
  Makefile:1256: recipe for target '_clean_arch/arm/imx-common' failed
  make: *** [_clean_arch/arm/imx-common] Error 2

I notice at least one file name conflict at the top directory.

  SPL - image for IMX
  spl - directory where SPL is built

This commit renames the former to a temporary name.

I guess there is few developers testing U-Boot on Cygwin.
If Cygwin support is mandatory, please consider to rename IMX image.
