8e365396d4 riscv/mb/qemu: fix DRAM probing
Current version of qemu raise an exception when accessing invalid
memory.  Modify the probing code to temporary redirect the exception
handler like on ARM platform.
Also move saving of the stack frame out to trap_util.S to have all at
the same place for a future rewrite.

TEST=boots to ramstage

2fa8caba50 lib/ramdetect: Limit probe size to function argument
This avoids probing above the function argument where other things than
DRAM could be mapped.

6b5bc77c9b treewide: Remove "this file is part of" lines
Stefan thinks they don't add value.

Command used:
sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool)

The exceptions are for:
 - crossgcc (patch file)
 - gcov (imported from gcc)
 - elf.h (imported from GNU's libc)
 - nvramtool (more complicated header)

The removed lines are:
-       fmt.Fprintln(f, "/* This file is part of the coreboot project. */")
-# This file is part of a set of unofficial pre-commit hooks available

06993ee729 lib: ramdetect: Register exception handlers for ARMv8
Register exception handlers to avoid a Synchronous External Abort
that is raised when you try to access a non-memory address on ARMv8.
An exception handler can jump over the faulting instruction.
This is the feature only for QEMU/AArch64.

bd4bcab8ad lib: Rewrite qemu-armv7 ramdetect
* Move armv7 RAM dection to a common place
* Enable it for all emulated platforms
* Use 32bit probe values and restore memory even on failure
* Use the new logic on the following boards:
** qemu-armv7
** qemu-riscv

Tested on qemu-system-riscv:
Fixes kernel panic due to wrong memory limits reported.
