Peter Maydell a9abb7c647 target/arm: Implement M-profile "minimal RAS implementation" 
For v8.1M the architecture mandates that CPUs must provide at
least the "minimal RAS implementation" from the Reliability,
Availability and Serviceability extension. This consists of:
* an ESB instruction which is a NOP
-- since it is in the HINT space we need only add a comment
* an RFSR register which will RAZ/WI
* a RAZ/WI AIRCR.IESB bit
-- the code which handles writes to AIRCR does not allow setting
of RES0 bits, so we already treat this as RAZ/WI; add a comment
noting that this is deliberate
* minimal implementation of the RAS register block at 0xe0005000
-- this will be in a subsequent commit
* setting the ID_PFR0.RAS field to 0b0010
-- we will do this when we add the Cortex-M55 CPU model
