Subject: [PATCH v2] mtd/maps: fix solutionengine.c printk format warnings

From: Randy Dunlap <rdunlap@...radead.org>

Fix 2 printk format warnings (this driver is currently only used by
arch/sh/) by using "%pap" instead of "%lx".
(or we could just cast the physical addresses to unsigned int)

Fixes these build warnings:

../drivers/mtd/maps/solutionengine.c: In function 'init_soleng_maps':
../include/linux/kern_levels.h:5:18: warning: format '%lx' expects argument of type 'long unsigned int', but argument 2 has type 'resource_size_t' {aka 'unsigned int'} [-Wformat=]
../drivers/mtd/maps/solutionengine.c:62:54: note: format string is defined here
  printk(KERN_NOTICE "Solution Engine: Flash at 0x%08lx, EPROM at 0x%08lx\n",
                                                  ~~~~^
                                                  %08x
../include/linux/kern_levels.h:5:18: warning: format '%lx' expects argument of type 'long unsigned int', but argument 3 has type 'resource_size_t' {aka 'unsigned int'} [-Wformat=]
../drivers/mtd/maps/solutionengine.c:62:72: note: format string is defined here
  printk(KERN_NOTICE "Solution Engine: Flash at 0x%08lx, EPROM at 0x%08lx\n",
                                                                    ~~~~^
                                                                    %08x
