[PULL 02/29] pnv/xive2: Add definition for the ESB cache configuration register |

From: Frederic Barrat <fbarrat@linux.ibm.com>
Add basic read/write support for the ESB cache configuration register
on P10. We don't model the ESB cache in qemu so reading/writing the
register won't do anything, but it avoids logging a guest error when
skiboot configures it:
qemu-system-ppc64 -machine powernv10 ... -d guest_errors
...
XIVE[0] - VC: invalid read @240
XIVE[0] - VC: invalid write @240
