Leopoldo Rodríguez 548b69f177 1.1 Phase C1: W5500 datasheet verification — 2 bugs fixed, Ethernet unblocked 
Checked against WIZnet W5500 datasheet v1.1.0 (official pin table):
- CONFIRMED correct: pin 23 RSVD->GND, pin 18 VBG floating, EXRES1 12.4k/1%,
  PMODE[2:0]=111 autoneg via pins 43-45, LINKLED/ACTLED pins 25/27 active-low
  sink topology, TXN/TXP/RXN/RXP order (1/2/5/6), SPI on 32-37
- BUG FIXED: RSVD pins 38-42 were floating; datasheet requires GND. Added
  5 GND stubs on U11 in the schematic + (net GND) on board pads 38-42
- BUG FIXED: TOCAP/1V2O caps were 10uF/4.7uF; datasheet requires 4.7uF/10nF.
  C90 -> 4.7uF, C91 -> 10nF (sch + board values; footprints unchanged)
- R83 board value harmonized to sch's 12.4k/1%
Magjack HR911105A: wiring matches the standard table (TX 1/2, RX 3/6,
TCT pin4->3V3_ETH, RCT pin5->6.8nF, internal Bob Smith). Bench-check with
DMM before flash: pins 4/5 CT assignment + LED anode/cathode on 9-12.
