This change adds support to Lock down the configuration of
extended BIOS region. This is done as part of
fast_spi_lockdown_cfg() so that it is consistent with the
other lockdown.
Change includes:
1. New helper function fast_spi_lock_ext_bios_cfg() added that
will basically set EXT_BIOS_LOCK.

This change enables support for configuration of extended BIOS
region decode window. This configuration needs to be performed
as early as possible in the boot flow. This is required to
ensure that any access to the SPI flash region below 16MiB in
coreboot is decoded correctly. The configuration for the extended
BIOS window if required is done as part of fast_spi_early_init().
Changes include:
1. Make a call to fast_spi_enable_ext_bios() before the bus master
and memory space is enabled for the fast SPI controller.
2. Added a helper function fast_spi_enable_ext_bios() which calls
fast_spi_get_ext_bios_window() to get details about the extended
BIOS window from the boot media map.
3. Depending upon the SPI flash device used by the mainboard and
the size of the BIOS region in the flashmap, this function will
have to perform this additional configuration only if the BIOS
region is greater than 16MiB
4. Adddditionally, set up the general purpose memory range
registers in DMI.

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)

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

Use 16bit write to avoid touching the upper two bytes that may cause
write cycle to fail in case a prior transaction has not completed.
This function sets the WRSDIS(Bit 11) and FLOCKDN (Bit 15) of the
SPIBAR + BIOS_HSFSTS_CTL. While WRSDIS is lockable with FLOCKDN,
writing both in the same cycle is guaranteed to work by design.
Avoid read->modify->write operation not to clear the RW1C bits
unintentionally.

Earlier 15ms time-out was kept for SPI transactions which was not
enough for SPI Erase transactions.
Increase the max time-out time to 5 secs which was present in SKL
before common code.
This increase in time-out won't disturb other SPI transactions like
Read, Write or Read Status, since, for those it will come out of
the loop once FDONE bit or FCERR bit is set.

BRANCH=none
TEST=Built and booted poppy and all SPI transactions succeeded.

Create Intel Common FAST_SPI Controller code.
This code contains the code for SPI initialization which has
the following programming -
* Get BIOS Rom Region Size
* Enable SPIBAR
* Disable the BIOS write protect so write commands are allowed
* Enable SPI Prefetching and Caching.
* SPI Controller register offsets in the common header fast_spi.h
* Implement FAST_SPI read, write, erase APIs.
