ARM: shmobile: Rework adding devices to PM domains on Mackerel
On SH7372 and Mackerel devices are added to PM domains through a series of rmobile_add_device_to_domain_td() calls where the last argument is always the same. This is quite inefficient, so add a common function for adding devices to PM domains that reads the domain-device pairs information from a table and use it during SH7372 and Mackerel initialization.
