ata: Add APM X-Gene SoC SATA host controller support

This patch adds support for the APM X-Gene SoC SATA host controller. In
order for the host controller to work, the corresponding SATA PHY driver
musts also be available.

v4:
* Remove the ID property in DT
* Remove the temporary PHY direct function call and use PHY function
* Change printk to pr_debug
* Move the IOB flush addresses into the DT
* Remove the parameters retrieval function as no longer needed
* Remove the header file as no longer needed
* Require v2 patch of the SATA PHY driver. Require slightly modification
in the Kconfig as it is moved to folder driver/phy and use Kconfig
PHY_XGENE_SATA instead SATA_XGENE_PHY.

v3:
* Move out the SATA PHY to another driver
* Remove the clock-cells entry from DTS
* Remove debug wrapper
* Remove delay functions wrapper
* Clean up resource and IRQ query
* Remove query clock name
* Switch to use dma_set_mask/dma_coherent_mask
* Remove un-necessary devm_kfree
* Update GPL license header to v2
* Spilt up function xgene_ahci_hardreset
* Spilt up function xgene_ahci_probe
* Remove all reference of CONFIG_ARCH_MSLIM
* Clean up chip revision code

v2:
* Clean up file sata_xgene.c with Lindent and etc
* Clean up file sata_xgene_serdes.c with Lindent and etc
* Add description to each patch

v1:
* inital version
