Stephen Rothwell 8be35bdeb2 net/ehea: use consistant type 
ehea_plpar_hcall9() takes an "unsigned long" array to return its results,
so change the arrays we pass to it to match.  This is currently only
64 bit code, so the transformation is actually a noop, but because
ehea_plpar_hcall9() copies the values of registers into the array,
if this was ported to a 32 bit hypervisor interface "unsigned long"
would probably still be the correct type.
