`.text' is equivalent to the `.section .text' directive.
The `.text' directive just before `.section ".text_bare_init"'
or just before `.section ".text_head_entry"' is redundant
so drop it.

poweroff: Allow to register poweroff handlers ...

Allow to register handlers for poweroff. This allows to have multiple
poweroff implementations in a single binary. The implementation is close

MIPS: drop redundant debug_ll_outhexw macro defines ...

The debug_ll_outhexw macro has no dependency on UART model
so we can remove it from UART-dependent header files (debug_ll_ns16550.h
and mach-ath79/.../debug_ll.h).

On the other hand the only debug_ll_outhexw user is MIPS nmon monitor
so we can move the debug_ll_outhexw macro to pbl_nmon.h.

arch: refresh defconfigs ...

The defconfig files are long untouched and a
make xy_defconfig; make savedefconfig usually generates quite
a different looking file. Refresh them to make it easier to generate
patches against the configs using
make xy_defconfig; make menuconfig; make savedefconfig

This has been done with the following script.

for a in arch/*; do
	arch=$(basename $a)
	for c in $a/configs/*; do
		config=$(basename $c)

	export ARCH=$arch
	make $config && make savedefconfig && mv defconfig $c
	done
done

bootm: Move bootm options to common/Kconfig ...

bootm has a C API, so the bootm options have to depend on the
option providing the bootm code (CONFIG_BOOTM), not on the
option providing the command (CONFIG_CMD_BOOTM). Fixing the
dependencies makes it possible to fully use bootm from C without
enabling the bootm command support.
This also removes the CMD_ prefix from the options which means
we have to update the defconfigs aswell.
