ncsi: Add Get Version ID command
Get Version ID is one of the first commands used in NC-SI, because BMC's
use a lot of OEM NC-SI extensions, and you need to query the device's
manufacturer through Get Version ID before you can decide which OEM
NC-SI extensions to use.
The response format is documented in the NC-SI spec[1]. We're just
setting the NC-SI version supported to 1.0.0 (BCD-encoded[2]) and
returning the manufacturer's ID in network byte-order.
