The host won't keep asking for SETUP IN packets once it has received
the amount of data requested, so check to see if we've sent that much
and flip back to IDLE state if so.

This leaves most of the device configured across USB reset, which
appears to help when sending a IN reply to the first SETUP packet;
without this change, the IN reply would always get a length of 0,
which is fine for SET_ADDRESS, but not for GET_DESCRIPTOR_DEVICE,
which OS X appears to send before setting the address (go figure).

We were only using the low 8 bits of the setup packet reply max len,
which meant that if the other side sent a weird max len (as Windows 7
does), then we'd truncate our setup reply to whatever was in the low 8
bits of that value.

This involved carefully moving the USB away from the IRC before
turning it off.

This lets EasyMini be booted to idle mode by simply plugging it into USB.

Instead, just assign a fixed address in registers.ld. This avoids a
confusing section in the elf file.

No reason to have that in regular ram, and it means we've got space
for large enough stacks now

The lpc demo now has a USB command line.
Also allocates system stack so we know when ram is tight at build time
