sparc64: Fix clock event multiplier printf format.

sparc64: Fix clock event multiplier printf format.

The type got changed to u32, so %lx generated warnings
(and thus build failure on sparc64)

Stephen Rothwell fixed it like so:

-	printk("clockevent: mult[%lx] shift[%d]\n",
+	printk("clockevent: mult[%ux] shift[%d]\n",

But that's not a valid transformation, we now get:

clockevent: mult[51539607x] shift[32]

in the logs.

Fix it to use the correct plain "%x" instead.
