Tom Lendacky e505371dd8 x86/boot: Add early cmdline parsing for options with arguments
Add a cmdline_find_option() function to look for cmdline options that
take arguments. The argument is returned in a supplied buffer and the
argument length (regardless of whether it fits in the supplied buffer)
is returned, with -1 indicating not found.
