Per SMBIOS specs, The Type 0 BIOS Release Date is not a free form field but
must be specified in a US middle-endian format (mm/dd/yyyy), so make sure
we populate it accordingly by converting gcc's __DATE__ string. This is
required for platforms like Windows, that fail to parse the date otherwise.
Also, the system manufacturer should not be set to the same value as the
board manufacturer for the Type 1 strings, as, on the Raspberry Pi, this is
not representative of the actual manufacturer of the system, which is the
Raspberry Pi Foundation always.
It should be noted that we do not expect other compilers than ones using
a __DATE__ format similar to gcc's to be used for the foreseeable future.
