target-ppc: better support of e300 CPU core
Declare HID2 register. Use high BATs for e300 (8 instead of 4). Fix index of high BATs registers. Before the fix, IBAT4-7 were overwriting IBAT0-3. Signed-off-by: François Armand <francois.armand@os4i.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
