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.
