MIPS: XBurst: suitable solution for per-board debug_ll ...

In the commit 40492a0
(MIPS: add common header file for DEBUG_LL via NS16550)
introduced common DEBUG_LL via NS16550 for MIPS
(see file arch/mips/include/debug_ll_ns16550.h).

In the commit 1cbe2b2
(MIPS: XBurst: add Ritmix RZX-50 board support)
the file debug_ll_ns16550.h used in
the file arch/mips/mach-xburst/include/mach/debug_ll.h.

Usage looks like this:

------------------------------------------------
+#ifdef CONFIG_BOARD_RZX50
+#include <mach/debug_ll_jz4755.h>
+#endif
+
+#include <debug_ll_ns16550.h>
------------------------------------------------

So after adding another board (e.g. A320) we will have something like this:

------------------------------------------------
 #ifdef CONFIG_BOARD_RZX50
 #include <mach/debug_ll_jz4755.h>
 #endif

+#ifdef CONFIG_BOARD_A320
+#include <mach/debug_ll_jz4740.h>
+#endif

 #include <debug_ll_ns16550.h>
------------------------------------------------

This approach has disadvantage:
* the files mach/debug_ll_jz4740.h and mach/debug_ll_jz4755.h
(they go to arch/mips/arch-xburst) are __BOARD-SPECIFIC__
(not SOC- or mach-specific!); The file mach-xburst/include/mach/debug_ll.h
is outside board directory, but it contains some board related information.

This commit introduce a more suitable solution.

ARM startup: Do call __mmu_cache_flush during startup ...

Traditionally we call __mmu_cache_flush in early startup. There
is a problem with armv7 and hierarchical caches though, on these
systems __mmu_cache_flush uses the stack. Appearantly this was
seldomly a problem, because most of these systems have a ROM
bootloader which sets up some stack, but on a special i.MX6 system
this failed badly. We should not have to flush caches here. Every
sane system should pass control to the bootloader without stale
entries in the caches *), so it should be a safe assumption that the
cache flush can be removed.

Since __mmu_cache_flush is not called from early code anymore we can
also move it to the regular text section.

Be brave and give it a try.

*) omap3 seems to be a exception to this, but this has a cache flush
in arch_init_lowlevel already
