ipmi: introduce a struct ipmi_sdr_compact
Currently, sdr attributes are identified using byte offsets and this
can be a bit confusing.
This patch adds a struct ipmi_sdr_compact conforming to the IPMI specs
and replaces byte offsets with names. It also introduces and uses a
struct ipmi_sdr_header in sections of the code where no assumption is
made on the type of SDR. This leave rooms to potential usage of other
types in the future.
