net: phy: microchip_t1s: configure collision detection based on PLCA mode
As per LAN8650/1 Rev.B0/B1 AN1760 (Revision F (DS60001760G - June 2024))
and LAN8670/1/2 Rev.C1/C2 AN1699 (Revision E (DS60001699F - June 2024)),
under normal operation, the device should be operated in PLCA mode.
Disabling collision detection is recommended to allow the device to
operate in noisy environments or when reflections and other inherent
transmission line distortion cause poor signal quality. Collision
detection must be re-enabled if the device is configured to operate in
CSMA/CD mode.
