The BIOS Firmware Version in the SMBIOS Type 0 can be fetched from
the fixed PcdFirmwareVersionString or platform specific OemMiscLib.
In fact, the support from OemMiscLib comes into play when the firmware
version may be modified at boot time for extended information.
Therefore, the priority of getting the version from OemMiscLib should
be higher.
In case there is no modification in the OemMiscLib, we have to keep
HII string STR_MISC_BIOS_VERSION empty or 'Not Specified'
to indicate that the firmware version should be fetched from
the PcdFirmwareVersionString.

nit: this function comment seems a bit at odds with the name of the
function (i.e. the comment says it gets the FW version, but the name of
the function is SetBiosVersion, which I see was changed in this patch).
Perhaps updating the comment to indicate it retrieves the BIOS version
from OemMiscLib or PcdFirmwareVersionString and then sets it in SMBIOS.

Hi Tinh,
Sorry, was waiting for a v4 based on your last reply to Oliver.
Yes, from my end (with Oliver's feedback addressed):
