phy: qcom-ufs: Don't return error if fail to get optional resource
"dev_ref_clk_ctrl_mem" is optional resource, so don't return error if fail to get the resource. Since it's an optional resource, don't emit error if fail to get dev_ref_clk_ctrl_mem. Also remove redundant test for res, it's done by devm_ioremap_resource(). Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
