[POWERPC] Fix build errors when BLOCK=n

These are the symptom error messages:

The fix tries to use the smallest scope CONFIG_* symbols that will fix
the build problem.  In this case <linux/ide.h> needs to be included
only if IDE=y or IDE=m were selected.  Also, ppc_ide_md is needed only
if BLK_DEV_IDE=y or BLK_DEV_IDE=m

Moved the EXPORT_SYMBOL(ppc_ide_md) from ppc_ksysms.c next to its
declaration in setup_32.c which made <linux/ide.h> not needed. With
<linux/ide.h> gone from ppc_ksyms.c, <asm/cacheflush.h> is needed to
address the following warnings and errors:

  CC      arch/powerpc/kernel/ppc_ksyms.o
arch/powerpc/kernel/ppc_ksyms.c:122: error: '__flush_icache_range' undeclared here (not in a function)
arch/powerpc/kernel/ppc_ksyms.c:122: warning: type defaults to 'int' in declaration of '__flush_icache_range'
arch/powerpc/kernel/ppc_ksyms.c:123: error: 'flush_dcache_range' undeclared here (not in a function)
arch/powerpc/kernel/ppc_ksyms.c:123: warning: type defaults to 'int' in declaration of 'flush_dcache_range'
