[PATCH 3/4] rockchip: rk3568-rock-3a: Drop PCIe reset-gpios workaround

The GPIO2_D6 pin is changed to use func-4 using pcie30x2m1_pins during
probe of pcie3x2. This cause the device to lock-up when pci driver use
the reset-gpios unless the pin is first changed to use gpio pinmux.

Drop the board u-boot.dtsi workaround now that the gpio and pinctrl
drivers automatically use gpio pinmux when a gpio is requested.
