Subject: [PATCH v2 0/3] rockchip: small DTS fixes for RK3399 Puma

There's a pull-up missing on a pin that is used as GPIO input for PCIe
which will make the diode/level-shifter not let voltage pass and thus
not allowing the state of the pin to change.

Also add the missing regulators for the PCIe PHY+connector though this
is purely cosmetic.

There's also a missing PU on the USB ID pin used as a GPIO input, so
let's add it for the same reasons as the one used for PCIe listed above.

Note there's a light dependency on
https://lore.kernel.org/linux-rockchip/43d84aa9-ce0f-406e-82ac-2a691264ee23@theobroma-systems.com/T/#ma0499cbc5e5c20f1a4c6b8452baa2d296abe2d0d
to prevent a git conflict for the maintainer(s).
