[PATCH v2 15/21] serial_lpuart: add clock enable if CONFIG_CLK is defined

[sbabic at denx.de]

> This driver assumes that lpuart clock is already enabled before probing
> but using DM only lpuart won't be automatically enabled so add
> clk_enable() when probing if CONFIG_CLK is defined. If clock is not
> found, because DM is not used, let's emit a warning and proceed, because
> serial clock could also be already enabled by non DM code. If clock is
> found but cna't be enabled then return with error.
