The prerequistes documentation should be updated because nowadays serial connections do work on arm64 with a 64-bit JVM.

See also: openhab/openhab-core#447

The current documentation states:

Please use the 32-bit version of the JVM for ARM platforms, even on 64-bit operating systems. Serial connections won't work with a 64-bit JVM, preventing bindings like Z-Wave from functioning.

This may cause people to put effort into recompiling the nrjavaserial library themselves (see community topic) eventhough it should already work out of the box with openHAB 2.4.0.

Maybe the documentation should warn that there might still be "other" add-ons that only work with a 32-bit JVM on ARM processors?

Update prerequisites
1d89395 
* Emphasize that Java 8 should be used which hopefully makes users double check their Java version
* Add recommendation for using 64-bit JVM on Intel/AMD
* Update recommendation for ARM with Raspberry Pi example so users can easier relate to it
* Update reasons for using 32-bit JVM on ARM so users don't put effort into recompiling nrjavaserial on arm64 because it already works

Fixes openhab#932
