Sumit Gupta ea88c6c781 PCI: tegra194: Fix possible array out of bounds access
[ Upstream commit 205b3d02d57ce6dce96f6d2b9c230f56a9bf9817 ]

Add check to fix the possible array out of bounds violation by
making speed equal to GEN1_CORE_CLK_FREQ when its value is more
than the size of "pcie_gen_freq" array. This array has size of
four but possible speed (CLS) values are from "0 to 0xF". So,
"speed - 1" values are "-1 to 0xE".
