HID: add quirk for Freescale i.MX23 ROM recovery

The USB recovery mode present in i.MX23 ROM emulates USB HID.
It needs this quirk to behave properly.

Even if the official branding of the chip is Freescale i.MX23,
I named it Sigmatel STMP3780 since that's what the chip really
is and it even reports itself as STMP3780.

Applied, thanks Marek.

Thank you. It'd be nice to queue this for -stable too.

Can we possibly push this into -stable please?

What is the git commit id of it in Linus's tree?  I need that before it
can go into a stable release.

This 436136cec650d661eb662fcb508a99878606d050 should be it, right ?

Thank you! I'll remember to supply the ID next time I prod anyone about stable 
stuff.

Ah, yes, that looks correct.

That would be great, that's all I really need in order to be able to
apply a patch.
