[PATCH 05/11] board: freescale: p1_p2_rdb_pc: Fix page attributes for second 1G SDRAM map

["Pali Rohár" <pali@kernel.org>]

Like for first 1G SDRAM map, do not enable Caching-inhibited nor Guarded
attribute for second 1G SDRAM mapping. Whole 2G SDRAM should use caches and
also allow speculative loading (by not setting Guarded attribute).

Also enable Memory Coherency attribute for second 1G SDRAM map. In commit
316f0d0f8f3c ("powerpc: mpc85xx: Fix static TLB table for SDRAM") it was
enabled for all SDRAM maps on all other boards, just missed this one case.

As a last thing, first 1G SDRAM map has wrong comment, so adjust it.
