riscv: Fix orphan section warnings caused by kernel/pi
kernel/pi gives rise to a lot of new sections that end up orphans: the first attempt to fix that tried to enumerate them all in the linker script, but kernel test robot with a random config keeps finding more of them. So prefix all those sections with .init.pi instead of only .init in order to be able to easily catch them all in the linker script.
