schematic: eFuse OVLO ladder + ILIM fix (V2.1)

Browse Source 
Implements the values worked out in 6ce7657.

  R45  100k -> 33k    ILIM 0.52 A -> 1.52 A (clears the 621 mA inrush)
  R46  620k -> 150k   ladder R1: 12V_RAW -> EN/UVLO
  R47  100k -> 10k    ladder R2: EN/UVLO -> OVLO
  R48  NEW    12k  \  ladder R3 = 14.2k: OVLO -> GND
  R49  NEW    2.2k /
  U13 pin 2 (OVLO) taken off GND and onto the new EFUSE_OVLO net

Verified: netlist shows 12V_RAW(R46.1) / EFUSE_EN(R46.2,R47.1,U13.5) /
EFUSE_OVLO(R47.2,R48.1,U13.2) / EFUSE_R3MID(R48.2,R49.1) / GND(R49.2,R45.2,
U13.4); 150 -> 152 components with none dropped (the malformed-property trap
from the kicad-bom-edit skill); ERC 0 violations.

PCB placement and routing still to do.
