kgdb,kdb: individual register set and and get API
The kdb shell specification includes the ability to get and set
architecture specific registers by name.
For the time being individual register get and set will be implemented
on a per architecture basis. If an architecture defines
DBG_MAX_REG_NUM > 0 then kdb and the gdbstub will use the capability
for individually getting and setting architecture specific registers.
