Add driver to read 'hwid' file from CBFS and use it for SMBIOS product
name. Processes the ChromeOS-format HWID string by removing prefix
after colon, trimming whitespace, and extracting base name before
any hyphen/space. Returned string is normalized to have the first
character/letter capitalized, and the rest lower case. If no HWID file
is found in CBFS, the fallback is CONFIG_MAINBOARD_SMBIOS_PRODUCT_NAME.
This driver is intended to allow ChromeOS devices running upstream
coreboot to persist their board's unique HWID and use it as the SMBIOS
board name, but it is not limited to that function.
TEST=tested in MrChromebox downstream. Multiple devices which use the
same ChromeOS board but differ in HWID can use the same firmware image
and still be properly identified.
