powerpc/powernv: Silence SYSPARAM warning on boot
OpenPower BMC machines do not place any sysparams in the device tree, so at every boot we get a warning: [ 0.437176] SYSPARAM: Opal sysparam node not found Remove the warning, and reorder the init so we don't peform allocations when there is no sysparam node in the device tree.
