chromebook_coral: Move CONFIG_BLOBLIST_ADDR to CAR
Reading doc/board/google/chromebook_coral.rst we can see that at some
point it was intended to put the bloblist in CAR, rather than DRAM, at
some point during development. This is fine for TPL/SPL stages where we
have very minimal information stored in the bloblist and so we can set
the limit there to 4KiB and then expand it to 196KiB in U-Boot proper so
there's room for ACPI tables and so forth. We also update the
documentation to use the same location for CONFIG_BLOBLIST_ADDR in both
references.
