JC4880P443-19 WIP - Fix OV02C10 2-lane register 0x4837 to restore working baseline

CRITICAL FIX: Reverted register 0x4837 from 0x10 back to 0x15

Problem:
- Changed 0x4837 from 0x15 to 0x10 (based on Linux ipu6 driver reference)
- ALL VTS values (323, 582, 900, 1164) produced blank frames (0xffff)
- Even original working VTS=1164 failed with blank frames
- Sensor detected correctly (PID=0x5602) but no valid image data

Root Cause:
- Register 0x4837 (MIPI PCLK Period) is PLL/clock-dependent
- Linux driver uses different PLL config (0x0305=0xe0 vs our 0x90)
- Cannot directly copy individual register values between implementations

Solution:
- Reverted 0x4837 from 0x10 back to 0x15 (original value)
- IMMEDIATELY restored working baseline
- Real camera frames at stable 8.3fps (120.24ms intervals)
- Pixel data: 0x1082, 0x18a3 (not blank 0xffff)

Results:
✅ Frame rate: 8.314 fps (120,240-120,283 µs intervals)
✅ Real pixel data: Start=0x1082, Mid=0x18a3, End=0x1082
✅ No timeouts: Continuous streaming without 1-second warnings
✅ Stable operation: Consistent frame intervals

Key Learning:
Register 0x4837 MUST stay at 0x15 for our ESP-IDF PLL configuration.
Linux driver's 0x10 value only works with their different clock setup.

Next Steps:
- Keep 0x4837=0x15 fixed
- Attempt VTS reduction carefully to improve frame rate
- Only modify VTS/HTS registers for frame rate tuning
