PCI: exynos: Split into Synopsys part and Exynos part
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.
