bus-scan-delay-ms property is not used anywhere in the code. This was found
while preparing a workaround patch using equally named property for
RockPro64 [1] which uses the same RK3399 SoC as Pinebook Pro.

bus-scan-delay-ms might have been picked to Pinebook Pro DT from my earlier
patches for RockPro64 custom kernels like [2] or [3].

Hello all,

Sending this as RFC because I don't have Pinebook Pro to test the cleaned
up DT and can only check that the change doesn't break the build. I did not
find any code reference to removed property and believe it has been
accidentally copied over, but there could always be some surpise.

Testing and comments how to proceed are welcome.
