[Skiboot] [PATCH] hdata: Fix SP attention area address

[Vasant Hegde]

SP attention area is aligned. We were sending wrong address.
Hence `attn` on FSP based system is failing. Align SP attention
area so that FSP can locate attention data.

Fixes: 518e554 (spira: fix endian conversions in spira data structures)
