It's an unfortunate side effect of our different-archs-per-stage
mechanism that all src/arch/*/Kconfig files are always parsed with no
if blocks to exclude them if they're not relevant. This makes it very
easy to accidentally rely on a Kconfig default set by a totally
different and not applying architecture.
This patch moves a few Kconfigs from ARM and X86 that leaked out like
this into a common Kconfig file for clarity. It also gives ARM64 its
own BOOTBLOCK_CUSTOM mechanism so that it doesn't leech off the ARM one
(currently not used by any board).
In the future, we should maybe prefix all options in the arch/*/Kconfig
files with the architecture name (such as X86_BOOTBLOCK_NORMAL and
ARM_LPAE are already doing), to make it more apparent when they are used
in the wrong place.

A branch instruction in a branch delay slot confuses the execution
pipeline and causes an exception.
bootblock.S was written 'by hand', has a branch instruction in branch
delay slot and includes '.set noreorder' directive, which causes it to
crash when trying to branch to main().
Adding a nop instruction fixes the problem. Also adding a nop after
the last branch in the file just in case main() returns and the object
linked next starts with a branch.

The ARM SMP feature was added a long time ago and has never really been
used by anyone since. We are still always compiling cpu_info() even
though we don't use it, and it makes some dangerous assumptions about
stack alignment that are not guaranteed anywhere.
I'm planning to change the way the stack boundaries are defined. Rather
than trying to work that into this unsafe, unused and hard to test
feature, I think we should just seal it off with police tape and make
sure that if anyone ever tries to use it again (which currently seems
unlikely), they get forced to do their due diligence on making sure it
works as intended.

Transition library provides the following functionalities:
1) Setup the environment for switching to any particular EL and jump to the
loaded program at that EL. In short "Execute program X at exception level Y
using the state Z"
2) Provides routines for exception entry and exception exit that can be used by
any program to implement exception handling. The only routine required by the
program would be exc_dispatch which handles the exception in its own required
way and returns by making a call to exc_exit. On exc_exit, the transition
library unwinds the whole stack by popping out the saved state of xregs
