Adding dynamic USB power support

- Each scan module now has a current change callback which passes the available current as a parameter
- No longer attempts to use the max 500 mA immediately, starts with 100 mA then goes to 500 mA after enumeration
- If enumeration fails due to bMaxPower of 500 mA, then attempt again at 100 mA (might also be possible to go even lower to 20 mA in certain cases)
- Now working with the Apple Ipad (no over-power messages)
- Fixed Wake-up behaviour on Apple Ipad (and likely other iOS devices)
- More effecient set_feature/clear_feature handling (device handler)
- Initial power handling via Interconnect (still needs work to get it more dynamic)

// XXX Power negotiation hack -HaaTa
// Some devices such as the Apple Ipad do not support bMaxPower greater than 100 mA
// However, there is no provision in the basic USB 2.0 stack for power negotiation
// To get around this:
// * Attempt to set bMaxPower to 500 mA first

// (Descriptor with bMaxPower in it)
// * Change usb_bMaxPower to 50 (100 mA)

// According to notes online, it says that some Apple devices can only do 20 mA
// However, in my testing this hasn't been the case
// (you can also draw as much current as you want if you just lie in the descriptor :P)
