Kconfig: Update prompt and help text for CBFS_SIZE

Kconfig item CBFS_SIZE is actually indicating the host firmware
size, a.k.a. coreboot owned flash region size, covering
CBFS, FMAP, console, MRC cache, VPD, etc. Revise the prompt and
help documentation to reflect recent usage updates.

This is the part of the ROM actually managed by CBFS, located at the
end of the ROM (passed through cbfstool -o) on x86 and at the start
of the ROM (passed through cbfstool -s) everywhere else. It defaults
to span the whole ROM on all but Intel systems that use an Intel Firmware
Descriptor. It can be overridden to make coreboot live alongside other
components like ChromeOS's vboot/FMAP or Intel's IFD / ME / TXE
binaries. This symbol should only be used to generate a default FMAP and
is unused when a non-default fmd file is provided via CONFIG_FMDFILE.
