start-arm: disable I-cache ...

<HACK>

For some yet unknown reason the processor on the i.MX35 3stack board (at
least on our board) has problem with an activated instruction cache and
booting from NAND: The copy-from-NFC-RAM-to-SDRAM routine doesn't loop.

It looks basically like this:

1:
	ldmia
	stmia
	cmp
	ble 1b

If the "cmp" instruction lives on address 0xbb000640 it doesn't work
with an activated i-cache. The processor flags are not properly updated.
So the ble won't jump back. This obviously break booting from nand.

This is why this patch disables the i-cache.

</HACK>

When checking if we have to relocate ourselves, use _stext instead
of TEXT_BASE. TEXT_BASE might be the location of a pre image header.

[memory layout]: streamline memory layout ...

Memory layout can now be specified via kconfig options. Two
possibilities exist: default layout means the layout is stack

for each TEXT_BASE / stack / malloc heap.

as we rather use positive logic. Make it dependent on boards that
have it rather than on ARM
