libata: kill port_info->sht and ->irq_handler
libata core layer doesn't care about sht or ->irq_handler. Those are only of interest to the LLD during initialization. This is confusing and has caused several drivers to have duplicate unused initializers for these fields. Currently only sata_nv uses these fields. Make sata_nv use ->private_data, which is supposed to carry LLD-specific information, instead and kill ->sht and ->irq_handler. nv_pi_priv structure is defined and struct literals are used to initialize private_data. Notational overhead is negligible. Signed-off-by: Tejun Heo <htejun@gmail.com>
