a3423b3f23 acpi: Use U-Boot version for OEM_REVISION
OEM_REVISION is 32-bit unsigned number. It should be increased only when
changing software version. Therefore it should not depend on build time.

Change calculation to use U-Boot version numbers and set this revision
to date number.

Prior this change OEM_REVISION was calculated from build date and stored in
the same format.

After this change macro U_BOOT_BUILD_DATE is not used in other files so
remove it from global autogenerated files and also from Makefile.

bc21ccbaaa version: Remove global macro U_BOOT_VERSION_STRING from version.h
Version string is available in global variable char version_string[].
Macro U_BOOT_VERSION_STRING is not used by any other file, so remove it
completely from version.h. Other files were already converted to use
variable version_string[].

11275e4f72 smbios: Fix calculating BIOS Release Date
BIOS Release Date must be in format mm/dd/yyyy and must be release date.
U-Boot currently sets BIOS Release Date from U_BOOT_DMI_DATE macro which is
generated from current build timestamp.

Fix this issue by setting U_BOOT_DMI_DATE macro to U-Boot version which is
better approximation of U-Boot release date than current build timestamp.
Current U-Boot versioning is in format yyyy.mm so as a day choose 01.

Some operating systems are using BIOS Release Date for detecting when was
SMBIOS table filled or if it could support some feature (e.g. BIOS from
1990 cannot support features invented in 2000). So this change also ensures
that recompiling U-Boot from same sources but in different year does not
change behavior of some operating systems.

Macro U_BOOT_DMI_DATE is not used in other file than lib/smbios.c
so remove it from global autogenerated files and also from Makefile.

68f6a90ec2 Makefile: Provide numeric versions
For SMBIOS we want to store the numeric version numbers in the tables. It
does not make sense to parse the strings. Instead, add new #defines with
the version and patchlevel.

9b95f3f7ff README: Add doumentation for version information
There are quite a few available version options in U-Boot. Add a list of
the available Makefile variables and #defines, along with examples.
