Floppy Controller adds 10-15 seconds of boot (POST) time for EFI VMs

Description
To reproduce:
- Create a new VM (I usually use Linux x64 as template) with some (empty) hard disk
- On the System tab, enable EFI
- Boot it. It should boot to EFI shell rather quickly.
- Add a Floppy Controller (does not matter if you also attach drives to it)
- Boot it again. Notice that it now takes 10-15 seconds more before EFI shell starts.
This is also reproducible when booting from a medium, not only for the EFI shell. Also, the Boot Menu (opened with F12) feels more sluggish (~5 seconds delay) when a floppy controller is attached.
I know, floppies are outdated, but for EFI development they are one of the fastest way to deploy freshly (on the host) built EFI binaries into the VM.
[thanks to klaus-vb in IRC for the tip to try a fixed-size VMDK instead.]

for help on using tickets.
Not reproducible with a recent VirtualBox release so likely fixed by an EFI firmware upgrade on our side. Please reopen if still an issue on your end and provide a VBox.log from the affected VM as well.
