[PATCH] PCI: exynos: remove redundant code in exynos_pcie_establish_link

[Pankaj Dubey]

From: Anvesh Salveru <anvesh.s at samsung.com>

In exynos_pcie_establish_link if driver is not using generic phy,
we are resetting PHY twice, which is redundant, so this patch removes
repeated lines of code for PHY reset.
