remoteproc: Use size_t type for len in da_to_va
With upcoming changes in elf loader for elf64 support, section size will
be a u64. When used with da_to_va, this will potentially lead to
overflow if using the current "int" type for len argument. Change
da_to_va prototype to use a size_t for len and fix all users of this
function.
