In pursuit of the goal of eliminating the proliferation of raw region
devices to represent CBFS files outside of the CBFS core code, this
patch removes the get_spd_cbfs_rdev() API and instead replaces it with
spd_cbfs_map() which will find and map the SPD file in one go and return
a pointer to the relevant section. (This makes it impossible to unmap
the mapping again, which all but one of the users didn't bother to do
anyway since the API is only used on platforms with memory-mapped
flash. Presumably this will stay that way in the future so this is not
something worth worrying about.)

This patch adds the get_spd_sn function. It's for reading SODIMM serial
number. In spd_cache implementation it can use to get serial number
before reading whole SPD by smbus.
BUG=b:146457985
BRANCH=None
TEST=Wrote sample code to get the serial number and ran on puff.
It can get the serial number correctly.

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)
The removed lines are:

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.

From DDR4 SPD spec:
Byte 4 (0x004): SDRAM Density and Banks
Bits [7, 6]:
00 = 0 (no bank groups)
01 = 1 (2 bank groups)
10 = 2 (4 bank groups)
11 = reserved
Bit [5, 4] :
00 = 2 (4 banks)
01 = 3 (8 banks)
All others reserved
Separate DDR3 and DDR4 banks. And extened capmb, rows, cols and ranks.
Separate DDR3 and DDR4 ORGANIZATION/BUS_DEV_WIDTH offset.

Use the plain address instead of the weird shifted encoding (e.g. if
we'd use `0xa0` as address, it's actually `0x50` encoded into a write
command).

Instead of assuming the mapping of dimm number to SPD SMBus address,
allow the mainboard to provide its own mapping. That way, global
resources of empty SPD contents aren't wasted in order to address
a dimm on a mainboard that doesn't meet the current assumption.

Add library to:
1. add spd.bin in cbfs, generated from mainboard/spd/*.spd.hex files.
2. runtime get spd data with spd index as input.
3. fetch spd over smbus using early smbus functions.
