The cfg_read/write functions are DesignWare-specific. Add dw_pcie prefix
to avoid collision in global name space.

Without irq_create_mapping(), the correct IRQ number cannot be
provided. In this case, it makes problems such as NULL dereference.
Thus, irq_create_mapping() should be added for MSI.

The following variables and functions are used only in pcie-designware.c,
so make them static:
global_io_offset
dw_pcie_rd_own_conf()
dw_pcie_wr_own_conf()
dw_pcie_setup()
dw_pcie_scan_bus()
dw_pcie_map_irq()

Exynos PCIe IP consists of Synopsys specific part and Exynos
specific part. Only core block is a Synopsys Designware part;
other parts are Exynos specific.
Also, the Synopsys Designware part can be shared with other
platforms; thus, it can be split two parts such as Synopsys
Designware part and Exynos specific part.
