We have a timestamp from before cache-as-ram setup saved in the MMX
registers. Recover that timestamp, and use it as the base timestamp
rather than letting lib/bootblock.c use a late timestamp.
This allows more accurate profiling of the boot flow, since CAR setup
time is no longer excluded from the timing information.

timestamp_cache_get() would call timestamp_cache_init() whenever it
found a timestamp cache in the TIMESTAMP_CACHE_UNINITIALIZED state.
That means that timestamp_cache_get() will never reurn a cache in the
uninitialized state.
However, timestamp_init() checks against the uninitialized state, as
it does not expect timestamp_cache_get() to perform any initialization.
As a result, the conditional branch can never be reached.
Simply remove the timestamp_cache_init() call from timestamp_cache_get().

timestamp.c was not included in bootblock and postcar. This means that
these two stages would use the weak implementation in lib/timestamp.c
instead of the arch-specific implementation based on rdtsc.
This resulted in using timer_monotonic_get() which resets the
timestamps from 0. timer_monotonic_get() only provides per-stage
incrementing semantics on x86 because lapic implementation has
counting down values. A globally incrementing counter like rdtsc
provides the semantics like every other non-x86.
On the test configuration, the weak implementation of timestamp_get()
returned zero, resulting in wrong timestamps coming from the bootblock,
while romstage and ramstage used the arch implementation and returned
correct timestamps.
This is a great example of why weak functions are dangerous, and how
easy it is to miss subtle yet strong interactions between subsystems
and the coreboot buildsystem.

The libpayload CBFS APIs are pretty old and clunky, primarily because of
the way the cbfs_media struct may or may not be passed in and may be
initialized inside the API calls in a way that cannot be passed back out
again. Due to this, the only real CBFS access function we have always
reads a whole file with all metadata, and everything else has to build
on top of that. This makes certain tasks like reading just a file
attribute very inefficient on non-memory-mapped platforms (because you
always have to map the whole file).
This patch isn't going to fix the world, but will allow a bit more
flexibility by bolting a new API on top which uses a struct cbfs_handle
to represent a found but not yet read file. A cbfs_handle contains a
copy of the cbfs_media needed to read the file, so it can be kept and
passed around to read individual parts of it after the initial lookup.
The existing (non-media) legacy API is retained for backwards
compatibility, as is cbfs_file_get_contents() (which is most likely what
more recent payloads would have used, and also a good convenience
wrapper for the most simple use case), but they are now implemented on
top of the new API.

Using a dedicated variable is slightly less readable and makes the code
less consistent, given that other test functions are called directly in
the if statements.

Add helper functions for generating some common objects:
acpigen_write_STA(status) will generate a status method that will
indicate the device status as provided:
Method (_STA) { Return (status) }
Full status byte configuration is possible and macros are provided for
the common status bytes used for generated code:
ACPI_STATUS_DEVICE_ALL_OFF = 0x0
ACPI_STATUS_DEVICE_ALL_ON = 0xF
acpigen_write_PRW() will generate a Power Resoruce for Wake that describes
the GPE that will wake a particular device:
Name (_PRW, Package (2) { wake, level }

In order to produce smaller AML and not rely on the caller to size the
output type appropriately add a helper function that will output an
appropriately sized integer.
To complete this also add helper functions for outputting the single
OpCode for Zero and One and Ones.
And finally add "name" variants of the helpers that will output a
complete sequence like "Name (_UID, Zero)".
