[PATCH v3 2/2] smbios: fill wake-up type

[Heinrich Schuchardt]

We should not use the reserved value 0x00 for the wake up type but
use 0x02 (Unknown).

Signed-off-by: Heinrich Schuchardt <heinrich.schucha...@canonical.com>

v3:
        use an enum for the constants
v2:
        use wake-up type 'Unknown' as our default
        add more SMBIOS wake-up type constants
