[ion] 25852: - KPROCESSOR_STATE is not 4-byte aligned. - Fail physical memory reads for now. - Use the right kernel load address. - Generate image name when loading boot symbols. Now WinDBG sees "ntoskrnl.exe". - Fix KiSaveProcessorControlState and KiRestoreProcessorControlSate. The latter doesn't freeze the CPU anymore so it's enabled, and the former doesn't cause WinDBG to panic anymore and display weird data.

Log:
- KPROCESSOR_STATE is not 4-byte aligned.
- Fail physical memory reads for now.
- Use the right kernel load address.
- Generate image name when loading boot symbols. Now WinDBG sees
"ntoskrnl.exe".
- Fix KiSaveProcessorControlState and KiRestoreProcessorControlSate. The latter
doesn't freeze the CPU anymore so it's enabled, and the former doesn't cause
WinDBG to panic anymore and display weird data.
