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.

This commit does the same thing as Linux commit 33def8498fdd.
Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

Move this code into a generic location so that it can be used by other x86
boards which want to boot from coreboot. Also ensure that this is called
if booting from coreboot.

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 useful to be able to parse coreboot tables on any x86 build which is
booted from coreboot. Add a new Kconfig option to enable this feature and
move the code so it can be used on any board, if enabled.
