arm64: dts: rockchip: Use only supported PCIe link speed on Pinebook Pro

Browse Source 
On Pinebook Pro laptops with an NVMe SSD installed, prevent random
crashes in the NVMe driver by not attempting to use a PCIe link speed
higher than that supported by the RK3399 SoC.

See commit 712fa17772 ("arm64: dts: rockchip: add max-link-speed for
rk3399").
