Subject: [PATCH] auto-brightness: Change light debounce for R4/O6

This reduces the brightening and darkening light debounce
configuration to match R3 and earlier Pixel devices.

Bug: 185770517
Test: Verified "dumpsys display" shows correct config values.
      Verified brightness transitions are similar to R3 now.
