Sometimes coreboot adds new tags that U-Boot does not know about. These
are silently ignored, but it is useful to at least know what we are
missing.
Add a way to collect this information. For Brya it shows:
Unimpl. 38 41 37 34 42 40
These are:
LB_TAG_PLATFORM_BLOB_VERSION
LB_TAG_ACPI_CNVS
LB_TAG_FMAP
LB_TAG_VBOOT_WORKBUF
LB_TAG_TYPE_C_INFO
LB_TAG_BOARD_CONFIG

At present any ACPI tables created by prior-stage firmware are ignored.
It is useful to be able to view these in U-Boot.
Pick this up from the sysinfo tables and display it with the cbsysinfo
command. This allows the 'acpi list' command to work when booting from
coreboot.
Adjust the global_data condition so that acpi_start is available even if
table-generation is disabled.

Add a function comment for get_coreboot_info() and a declaration for
cb_get_sysinfo(), since this may be called from elsewhere.

Quite a few new tag types have been added over the years. Bring these into
U-Boot so that all required tags can be parsed.
Add a proper comment to struct sysinfo_t while we are here, since many of
the meanings are not obvious.

It is possible to boot U-Boot for chromebook_coral either 'bare metal' or
from coreboot. In the latter case we want to provide access to the coreboot
sysinfo tables. Move the definitions into a file available to any x86
board.
