When updating firmware, we may need to preserve some sections like VPD,
calibration data, ... etc. The logic can be hard-coded in updater as a
list of known names, but a better solution is to have that directly
declared inside FMAP area flags.
To do that, the first step is to apply the changes in flash map
(http://crosreview.com/1493767). A new FMAP_AREA_PRESERVE is now
defined and will be set in future with new syntax in FMD parser.

If keys are pressed at boot some keyboard controllers will not
properly respond with an ACK to commands, which results in the
keyboard_init function aborting before it adds the keyboard to the
input device list.
This same keyboard controller will manage to properly return keyboard
data when keys are pressed later, so it is possible for it to be
functional in the payload even if it does not respond properly to
every command during initialization.
In order to allow payloads to use the keyboard when this happens a
new Kconfig option is added to ignore the keyboard ACK response and
always add the keyboard to the input device list. This option is
disabled by default and must be enabled by the specific boards that
need it.

Rather than attempt to maintain patches against upstream Tianocore, use
MrChromebox's coreboot framebuffer branch as the default build target.
Rework the Makefile to default to MrChromebox's coreboot_fb branch, but
also allow for aribitrary commits from upstream Tianocore to be used
as build targets.
Ensure the branch is synced on each build, as long as working directory
is clean, and that switching between commits or trees is handled sanely.
Eliminate TIANOCORE_MASTER as a selectable build target, since unpatched
it is unlikely to boot on any device. It can easily be specified via
the 'revision' option if desired.
Test: build for the default stable target, for upstream/master
as the specified revision, and for an arbitrary valid commit hash.

This patch reworks the arm64 exception handling to be more similar to
how it works on arm32. This includes a bunch of features like actually
saving and restoring more exception state in the exception_state
structure and supporting the same sort of partial reentrancy that is
useful for GDB. Since there's no instruction to directly load into or
store out of SP on arm64, we can't do quite the same thing where we use
that to read an exception_state_ptr variable right after exception entry
when no other register is available. But we can do something very
similar by (ab-)using the "high" stack pointer (SP_EL2) as a pointer to
the exception_state struct and providing a function to change it.

This patch adds the new, faster architectural register accessors to
libpayload that were already added to coreboot in CB:27881. It also
hardcodes the assumption that coreboot payloads run at EL2, which has
already been hardcoded in coreboot with CB:27880 (see rationale there).
This means we can drop all the read_current/write_current stuff which
added a lot of unnecessary helpers to check the current exception level.
This patch breaks payloads that used read_current/write_current
accessors, but it seems unlikely that many payloads deal with this stuff
anyway, and it should be a trivial fix (just replace them with the
respective _el2 versions).
Also add accessors for a couple of more registers that are required to
enable debug mode while I'm here.
