Now that we have added MRC cache for Intel FSP and BayTrail codes,
enable it for all BayTrail boards (Bayley Bay and Minnow Max).

Note it turns out that FSP for Intel Atom E6xx does not produce
the HOB for NV storage, so we don't have such functionality on
Intel Crown Bay board.

fsp_init() call has a parameter nvs_buf which is used by FSP as the
MRC cache but currently is blindly set to NULL. Retreive the MRC
cache from SPI flash and pass it to fsp_init() call. After the call,
save FSP produced MRC cache to SPI flash too.

Currently struct fmap_entry is used to describe a mrc region.
However this structure contains some other fields that are not
related to mrc cache and causes confusion. Besides, it does not
include a base address field to store SPI flash's base address.
Instead in the mrccache.c it tries to use CONFIG_ROM_SIZE to
calculate the SPI flash base address, which unfortunately is
not 100% correct as CONFIG_ROM_SIZE may not match the whole
SPI flash size.

Define a new struct mrc_region and use it instead.

This adds mrccache_reserve(), mrccache_get_region() and
mrccache_save() APIs to the mrccache codes. They are ported
from the ivybridge implementation, but with some changes.
For example, in the mrccache_reserve(), ivybridge version
only reserves the pure MRC data, which causes additional
malloc() when saving the cache as the save API needs some
meta data. Now we change it to save the whole MRC date plus
the meta data to elinimate the need for the malloc() later.

So far VxWorks bootline can be contructed from various environment
variables, but when these variables do not exist we get these from
corresponding config macros. This is not helpful as it requires
rebuilding U-Boot, and to make sure these config macros take effect
we should not have these environment variables. This is a little
bit complex and confusing.

Now we change the logic to always contruct the bootline from
environments (the only single source), by adding two new variables
"bootdev" and "othbootargs", and adding some comments about network
related settings mentioning they are optional. The doc about the
bootline handling is also updated.
