powerpc/powernv: Fix opal_xscom_{read,write} prototype
The OPAL firmware functions opal_xscom_read and opal_xscom_write take a 64-bit argument for the XSCOM (PCB) address in order to support the indirect mode on P8. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: <stable@vger.kernel.org> [v3.13]
