On the SC7280, the clock source for gcc_pcie_1_pipe_clk_src must be the TCXO while gdsc is enabled. After PHY init successful clock source should switch to pipe clock for gcc_pcie_1_pipe_clk_src. Signed-off-by: Prasad Malisetty <redacted> ---

Maybe worth failing probe with if (!pcie->ops) just to be a little nicer here.
