ahci_probe consists of 3 steps: 1) Get resources (get mmio, clks, regulator) 2) Enable resources, handled by ahci_platform_enable_resouces 3) The more or less standard ahci-host controller init sequence This commit refactors step 1 and 3 into separate functions, so the platform drivers for AHCI implementations which need a specific order in step 2, and / or need to do some custom register poking at some time, can re-use ahci-platform.c code without needing to copy and paste it. Note that ahci_platform_init_host's prototype takes the 3 non function members of ahci_platform_data as arguments, the idea is that drivers using the new exported utility functions will not use ahci_platform_data at all, and hopefully in the future ahci_platform_data can go away entirely. tj: Minor comment formatting updates.
