With d53ecad92f some unused interrupt related code was removed.
However all of these options are currently unused. Rather than migrate
some of these options to Kconfig we just remove the code in question.
The only related code changes here are that in some cases we use
CONFIG_STACKSIZE in non-IRQ related context. In these cases we rename
and move the value local to the code in question.

While x86 is the only user and this could in principle be moved to

Certain boards come in different variations by way of utilizing daughter
boards, for example. These boards might contain additional chips, which
are added to the main board's busses, e.g. I2C.
The device tree support for such boards would either, quite naturally,
employ the overlay mechanism to add such chips to the tree, or would use
one large default device tree, and delete the devices that are actually
not present.
Regardless of approach, even on the U-Boot level, a modification of the
device tree is a prerequisite to have such modular families of boards
supported properly.
Therefore, we add an option to make the U-Boot device tree (the actual
copy later used by the driver model) writeable, and add a callback
method that allows boards to modify the device tree at an early stage,
at which, hopefully, also the application of device tree overlays will
be possible.

For ARMv8 Layerscape SoCs, secure memory and MC memorey are reserved
at the end of DDR. DDR is spit into two or three banks. This patch
reverts commit aabd7ddb and simplifies the calculation of reserved
memory, and moves the code into common SoC file. Secure memory is
carved out first. DDR bank size is reduced. Reserved memory is then
allocated on the top of available memory. U-Boot still has access
to reserved memory as data transferring is needed. Device tree is
fixed with reduced memory size to hide the reserved memory from OS.
The same region is reserved for efi_loader.

The BSS region may overlap with relocations. If we clear BSS we will
overwrite the start of the relocation area. This doesn't matter when running
from SPI flash, since it is read-only. But when relocating 64-bit U-Boot
from one place in RAM to another, relocation will fail because some of its
relocations have been zeroed.
To fix this, put the ELF fixup call before the BSS clearing call.

and architectures which use arch_cpu_init from machine/SoC level code
(arm, x86).
In order to clean this mess up & allow for both use cases, introduce a
new mach_cpu_init callback which is run immediately after arch_cpu_init.
