Subject: [PATCH] atusb: use 0402 as the preferred component size and replace
 bad TVS

We know from CNTR that the capacitance of the 0603 TVS (EPCOS CT0603M4G,
200 pF) is too large and can disturb the USB signal. The 0402 TVS
(Panasonic EZJ-P0V080GA, 100 pF) works much better.

Since we have lots of 0402 components already, just change the remaining
0603 to 0402, too.

- usb.sch (VR1, VR2, VR3): change from 0603 to 0402 and from 5V5 to 5V6
- usb.sch (C1, C2, R1): change from 0603 to 0402
- atrf.sch (R3): set footprint to 0402
- atusb.pro: replaced modules/mini-usb with modules/usb_a_plug
- atusb.pro: removed extension from components/balun-smt6.lib
- atusb.cmp: update footprints for above changes
- atusb.cmp: change 0402 to 0402-M and 0603 to 0603-M, for easier
  soldering
