This patch adds support for chip RTL8125cp. Its XID is 0x708. We apply
different and firmware for RTL8125cp.

v2: This patch fix one mistake on phy_modify_paged(phydev, 0xa43, 0x10,
0x0000, 0x1001) which is phy_modify_paged(phydev, 0xa43, 0x00, 0x0000, 0x1001) on patch v1.
v3: Set phy_modify_paged(phydev, 0xa43, 0x10, 0x0000, 0x0003), bit 0
means 'link speed 10m PLL OFF', bit 1 means 'ALDPS PLL OFF', bit 2 means
'ENABLE ALDPS', bit 12 means 'ALDPS XTAL OFF'.
v4: Fix some format mistakes.
v5: Rebase on latest net-next. No changes.
v6: Rename some bits of 0x0a43, such as LINK_SPEED_10M_PLL_OFF for
BIT(0) and ALDPS_PLL_OFF for BIT(1). Disable interrupt coalescing for
RTL_GIGA_MAC_VER_65.
