arm64: dts: qcom: lemans: Separate out ethernet card for ride & ride-r3

Ride & Ride-r3 in lemans/lemans-auto uses different ethernet cards
with different phy capabilities. Separate out the ethernet card
information from main board so that it can be reused for all the
variants of ride & ride-r3 platforms in lemans/lemans-auto.

Lemans/lemans-auto Ride uses 1G phy while Lemans/lemans-auto Ride-r3
uses 2.5G phy.

Introduce ethernet cards with 1G & 2.5G phy capabilities respectively:
  *-88ea1512.dtsi is for 2x 1G - SGMII (Marvell 88EA1512-B2) phy
  *-aqr115c.dtsi is for 2x 2.5G - HSGMII (Marvell AQR115c) phy
