net: stmmac: ingenic: convert to stmmac_pltfr_pm_ops

Browse Source 
Convert the Ingenic glue driver to use the generic stmmac platform
power management operations.

In order to do this, we need to make ingenic_mac_init() arguments
compatible with plat_dat->init() by adding a plat_dat member to struct
ingenic_mac. This allows the custom suspend/resume operations to be
removed, and the PM ops pointer replaced with stmmac_pltfr_pm_ops.

This will adds runtime PM and noirq suspend/resume ops to this driver.
