powerpc/prom_init: Replace __initdata with __prombss when applicable
This replaces all occurrences of __initdata for uninitialized data with a new __prombss Currently __promdata is defined to be __initdata but we'll eventually change that. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
