Axel Lin 52ea796b91 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().
