riscv: dts: spacemit: PCIe and PHY-related updates

Browse source

Define PCIe and PHY-related Device Tree nodes for the SpacemiT K1 SoC.

Enable the combo PHY and the two PCIe-only PHYs on the Banana Pi BPI-F3
board.  The combo PHY is used for USB on this board, and that will be
enabled when USB 3 support is accepted.

The combo PHY must perform a calibration step to determine configuration
values used by the PCIe-only PHYs.  As a result, it must be enabled if
either of the other two PHYs is enabled.
