With the old order of initialization the hcor pointer has been setup to the same address as Exynos EHCI base address (0x12110000 instead of 0x12110010). Such behaviour was caused by reading value of 0 instead of 0x10 from EHCI HCCPBASE register without doing proper clock initialization before.
To fix this problem hcor initialization has been moved after USB PHY setup. Now ehci_readl(&ctx->hcd->cr_capbase) returns correct value.
