ARM: Cleanup stack offset cargo cult ...

Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16
bytes from the stack top. This is unnecessary as on ARM we have a stack
that decrements before storing values. Substracting this offset probably
goes back to the U-Boot version we forked from. Stop this now.

ARM: boards: Harmonize barebox_arm_reset_vector() prototype ...

barebox_arm_reset_vector() is a global function but we never provided a
prototype anywhere. The prototypes differ for the different boards, so
to provide a common prototype we must harmonize them.

void barebox_arm_reset_vector(uint32_t r0, uint32_t r1, uint32_t r2)

Should be suitable for all boards.

remove the calls to these functions.

OMAP and i.MX boards: do not set console= commandline parameter in environment ...

This is not necessary since for OMAP and i.MX the console= parameter is
initialized by the serial driver.

defaultenv-2: Make use of nonvolatile variables ...

This moves the variable assignments previously done in /env/config-board
to non volatile variables in /env/nv/. This makes the settings adjustable
by the user without editing a file.

Most of the changes are simple conversions which for many boards makes
/env/config-board unnecessary. Some boards had some logic to assign
global.boot.default based on the current bootsource. This has been
moved to /env/init/bootsource. An additional check is added to not
overwrite a nv.boot.default should it exist.

ARM: change signature of barebox_arm_entry ...

Mostly to make it clear that boarddata needs to be
something we can dereference.

As this is a pretty invasive change, use the opportunity
to make the signature 64bit safe.
