[PATCH V3 0/8] PCI:Add SPEAr13xx PCie support

[Mohit Kumar]

First three patches are improvement and fixes for SPEAr13xx support.
Next patch modify phy-core driver for its initialization during
subsys_initcall(). Platform ahci driver is modified for phy hooks.
Patch#6 and 7 modify/add support for SPEAr13xx SATA and PCIe.

These patches are tested with SPEAr1310 evaluation board:
	- INTEL PRO 100/100 EP card
	- USB xhci gen2 card
 	- Above cards connected through LeCROY PTC switch

Modifications for SATA are tested with SPEAr1340-evb board

Changes since v2:
- Incorporated comments to move SPEAr13xx PCIe and SATA phy specific routines to
  the phy framework
- Modify ahci driver to include phy hooks
- phy-core driver modifications for subsys_initcall() 
 
Changes since v1:
- Few patches of the series are already accepted and applied to mainline e.g.
 pcie designware driver improvements,fixes for IO translation bug, PCIe dw
 driver maintainer. So dropped these from v2.
- Incorporated comment to move the common/reset PCIe code to the seperate driver
- PCIe and SATA share common PHY configuration registers, so move SATA
 platform code to the system config driver
Fourth patch is improves pcie designware driver and fixes the IO
translation bug. IO translation bug fix leads to the working of PCIe EP devices
connected to RC through switch.

PCIe driver support for SPEAr1310/40 platform board is added.

These patches are tested with SPEAr1310 evaluation board:
	- INTEL PRO 100/100 EP card
	- USB xhci gen2 card
 	- Above cards connected through LeCROY PTC switch
