pass: Add new struct pass_resource_memory to support memory h/w device

This patch adds the new 'struct pass_resource_memory' in order to
manage the memory[1] h/w device according to the requirements.

If the new requirements arise in the future, the new functions
will be added in the struct pass_resource_memory.
