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.
