The configuration of SPSR bits that mask processor exceptions is kinda
oddly hidden as an implict part of the transition() function right now.
It would be odd but not impossible for programs to want to be entered
with enabled exceptions, so let's move these bits to be explicitly set
by the caller like the rest of SPSR instead.
Also clear up some macro names. The SPSR[I] bit is currently defined as
SPSR_IRQ_ENABLE, which is particularly unfortunate since that bit
actually *disables* (masks) interrupts. The fact that there is an
additional SPSR_IRQ_MASK definition with the same value but a different
purpose doesn't really help. There's rarely a point to have all three of
xxx_SHIFT, xxx_MASK and xxx_VALUE macros for single-bit fields, so
simplify this to a single definition per bit. (Other macros in
lib_helpers.h should probably also be overhauled to conform, but I want
to wait and see how many of them really stay relevant after upcoming
changes first.)

This patch adds support for integrating the runtime-resident component
of ARM Trusted Firmware (github.com/ARM-software/arm-trusted-firmware)
called BL31. It expects the ARM TF source tree to be checked out under
$(top)/3rdparty/arm-trusted-firmware, which will be set up in a later
patch.
Also include optional support for VBOOT2 verification (pretty hacky for
now, since CBFSv1 is just around the corner and will make all this so
much better).

Rename Kconfig options for secmon and spintable to be prefixed with
ARM64_ instead of ARCH_, which seems to be the standard throughout the
rest of coreboot (e.g. ARM_LPAE or X86_BOOTBLOCK_SIMPLE). I think this
provides a clearer separation between generic options that are selected
by the architecture (e.g. a hypothetical ARCH_HAS_FEATURE_X similar to
some of the MAINBOARD_HAS_... we have) and options that only make sense
in the context of a single architecture.

GICv2 provides a wake IRQ/FIQ (for wake-event purpose), which are not
disabled by GIC CPU interface. This is done by adding a bypass override
capability when the interrupts are disabled at the CPU interface. To
support this, there are four bits about IRQ/FIQ BypassDisable in CPU
interface Control Register. So the CPU can exit from WFI when an
asserted IRQ is coming. This is critical for power gating a CPU.

Inclusion of ricoh driver was lost in 1d7b9de350.
So the relevant code wasn't even compiled.
Fix copy-paste mistakes without significance while on it as well.

The spi_flash API did not have any of its callbacks
documented. Do that so that people don't have to go
into the guts of an implementation to figure out the
proper expectations.

Provide common code for using memory-backed region devices.
This allows in-memory buffers to act as a region device.

The memory pool infrastructure provides an allocator with
very simple free()ing semantics: only the most recent allocation
can be freed from the pool. However, it can be reset and when
not used any longer providing the entire region for future
allocations.

The region infrastructure provides a means of abstracting
access to different types of storage such as SPI flash, MMC,
or just plain memory. The regions are represented by
region devices which can be chained together forming subregions
of the larger region. This allows the call sites to be agnostic
about the implementations behind the regions. Additionally, this
prepares for a cleaner API for CBFS accesses.

Routing is decided based on enabled logical/virtual devices.
For a valid devicetree, one should have only one of SP3 and GPIO0,
and only one of SP4 and GPIO1, enabled at a time in configuration.
