Openrisc gdb patches after yao's comments

Hi All,

I wanted to circulate these patches on the openrisc list first. These are in response to Yao's gdb patch review.

- The first patch is baiscally format and comment updates as per gnu style.
- The second removes the unimplemented pseudo register functions
- Next is the BIG one it removes the handling of target-description parsing and intercepting. But this is as per the recommended way. May what is questionable is how I hard code the reggroups.
- Next removes the special spr commands. I think or1ksim would need to be updated to work with the target-descriptor xml.
- Last is just a cleanup.

The plan would be to squash all of these into the previous patch set I sent.

Test results look ok. Also I tested against openocd and I can reed sprs with commands like info reg upr as expected.
