[U-Boot] [PATCH] cmd_flash.c: fix compile error for boards with DataFlash

[Alessandro Rubini <rubini-list@gnudd.com>]

From: Alessandro Rubini <rubini@gnudd.com>

The local variables addr_first and addr_last are used if HAS_DATAFLASH
even if SYS_NO_FLASH (meaning no NOR flash). This adds the definitions
withing the brace where the names are used, to avoid cluttering the
initial ifdef.

5 boards were not compiling with "./MAKEALL arm", now they all work.
Actually, even at91sam9263ek_nandflash_config was in error, but it's
not one of the MAKEALL targets. Should MAKEALL test all possible configs or not?
