[Skiboot] [PATCH RESEND] platforms/astbmc: Don't validate model on palmetto

[Gavin Shan]

The platform isn't compatible with palmetto until the root device-tree
node's "model" property is NULL or "palmetto". However, we could have
"TN71-BP012" for the property on palmetto.

   linux# cat /proc/device-tree/model
   TN71-BP012

This skips the validation on root device-tree node's "model" property
on palmetto, meaning we check the "compatible" property only.
