arm64: dts: rockchip: remove dangerous max-link-speed from helios64

Browse Source 
Shawn Lin from Rockchip strongly discourages attempts to use their
RK3399 PCIe core at 5.0 GT/s speed, citing concerns about catastrophic
failures that may happen. Even if the odds are low, drop from last user
of this non-default property for the RK3399 platform, helios64 board
dts.
