Sometimes we may need get (optional) clock without a device,
that means use ofnode.
e.g. when the phy node has subnode, and there is no device created
for subnode, in this case, we need these new APIs to get subnode's
clock.

For CMD21 tuning data, the 128/64 bytes data may coming in very

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.
