vmlinux.lds.h: lower init ramfs alignment to 4
The new init ramfs format (cpio based) requires an alignment of 4 (per the
documentation and per the source files themselves). As for compressed
sources, the decompressors can all deal with unaligned buffers.
The cpio source is also found in the __init sections of the kernel, so
once they are read and expanded into a tmpfs, the source is freed. That
means there is no need to force page alignment here either.
This has been used on Blackfin systems for many releases without issue.
