Rename the enums to match the naming style used by QAPI. This
will allow us to more easily move the enum to the QAPI schema
later.
Based on portions of a patch submitted by Daniel P. Berrangé.

From: Daniel P. Berrangé <berrange@redhat.com>
The i440fx and Q35 machine types are both hardcoded to use the legacy
SMBIOS 2.1 entry point. This is a sensible conservative choice because
SeaBIOS only supports SMBIOS 2.1
EDK2, however, can also support SMBIOS 3.0 and QEMU already uses this on
the ARM virt machine type.
This adds a property to allow the choice of SMBIOS entry point versions
For example to opt in to version 3.0
$QEMU -machine q35,smbios-ep=3_0

Just one small point: wouldn't it be a good idea to eschew
abbreviation here, and call the property smbios-entry-point
or even smbios-entry-point-type or smbios-entry-point-version?

Eduardo,
do you plan to submit Seabios patches for SMBIOS 3.0?
will OVMF pick up new tables automatically?
