serial_lpuart: add clock enable if CONFIG_CLK is defined
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.
