Subject: u-boot-sam460ex: build fixes

Fixes or works around numerous build issues and one real bug.

Most are due to new defaults in gcc (in debian), like
 -Werror=implicit-function-declarations (there are a lot of missing decls)
 -Werror=incompatible-pointer-types (function types mismatches)
 -Werror=int-conversion (free int <=> pointer conversion)
