Do not recommend deprecated legacy console #203

Section 8.3.9, "SPCR", says:

When SPCR describes SBI console, the OS must use the SBI Probe extension (FID #3) to detect the appropriate facilities, e.g. the Debug Console Extension (DBCN) or the deprecated legacy console EIDs.

The Architecture Review Committee does not believe the RISC-V BRS document should recommend using the deprecated legacy console. Instead, there should be a mandatory requirement earlier in the document stating that the DBCN SBI extension must be used when the SBI console is employed.

I agree. We should just mandate SBI DBCN when SPCR says SBI console. @andreiw @avpatel - any concerns?
