Call OpenSBI in M-Mode and use it to set up SBI and to lockdown the
platform. It will also jump to the specified payload when done.
This behaviour is similar to BL31 on aarch31.
The payload is 41KiB in size on qemu.
Tested on qemu-riscv:
Required to boot a kernel as OpenSBI's instruction emulation feature
is required on that virtual machine.
Tested on SiFive/unleashed:
The earlycon is working. No console after regular serial driver
should take over, which might be related to kernel config.

In order to de-duplicate common patterns implement one write_tables()
function. The new write_tables() replaces all the architecture-specific
ones that were largely copied. The callbacks are put in place to
handle any per-architecture requirements.

Add a architecture specific function, arch_write_tables(), that
allows an architecture to add its required tables for booting.
This callback helps write_tables() to be de-duplicated.

A architecture-specific function, named bootmem_arch_add_ranges(),
is added so that each architecture can add entries into the bootmem
memory map. This allows for a common write_tables() implementation
to avoid code duplication.

Each arch was calling cbmem_list() in their own write_tables()
function. Consolidate that call and place it in common code
in write_coreboot_table().

Instead of hard coding a #define in each architecture's
tables.c for the coreboot table size in cbmem use a Kconfig
varible. This aids in aligning on a common write_tables()
implementation instead of duplicating the code for each
architecture.

Add lb_arch_add_records() to allow the architecture code to
generically hook into the coreboot table generation.
BUG=chrome-os-partner:50214
BRANCH=glados
TEST=With all subsequent patches confirmed lb_arch_add_records() is
called when a strong symbol is provided.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

Until we completely can unify early_variables, use these to
handle CBMEM update hooks for both romstage and ramstage.
For x86, CAR_MIGRATE serves the purpose of romstage hooks.

Works in the RISCV version of QEMU.
Note that the lzmadecode is so unclean that it needs a lot of work.
A cleanup is in progress.
We decided in Prague to do this as one thing, because it forms a nice case study
of the bare minimum you need to add to get a new architecture going in qemu.
