Makefile: Rename u-boot-spl.kwb to u-boot-with-spl.kwb

File name with pattern u-boot-spl* is used on all places except in kwb
image for binary with SPL-only code. Combined binary with both SPL and
proper U-Boot in other places has file name pattern u-boot-with-spl*.

Make it consistent also for kwb image and rename u-boot-spl.kwb to
u-boot-with-spl.kwb as this image contains both SPL and proper U-Boot code.

Also update documentation about file name changes.

 The resulting image including the SPL binary with the
-full DDR setup is "u-boot-spl.kwb".
+full DDR setup is "u-boot-with-spl.kwb".
 
 Now all you need to do is copy this image on a SD card.
 For example with this command:
 
-$ sudo dd if=u-boot-spl.kwb of=/dev/sdX bs=512 seek=1
+$ sudo dd if=u-boot-with-spl.kwb of=/dev/sdX bs=512 seek=1
 
 Please use the correct device node for your setup instead
 of "/dev/sdX" here!

 Note that the SD card is not accessible when the Clearfog SOM has eMMC.
 Consider initial boot from UART (see below).
