DynamicTablesPkg: AML Code generation for memory ranges
Add helper functions to generate AML Resource Data describing memory
ranges. Memory ranges can be one, double or four words long. They
can be of 'normal', IO or bus number memory type. The following
APIs are exposed:
- AmlCodeGenRdDWordIo ()
- AmlCodeGenRdDWordMemory ()
- AmlCodeGenRdWordBusNumber ()
- AmlCodeGenRdQWordMemory ()
