Commit 71066545b48e4("driver core: Set fw_devlink.strict=1 by default")
default set fw_devlink to true. This has a side effect to i.MX uart
console. The sdma will make the i.MX8MP uart driver defer probe for some
time (~10s with i.MX8MP-EVK board) until sdma ready, because sdma is a
supplier with property dmas set in device tree node.

Since this uart is for console, we need log printed out as soon as
possible, so remove the dmas property for the uart console node.

Signed-off-by: Peng Fan <peng.fan@nxp.com>

V1:
 The upper set fw_devlink.strict=1 patch is in linux-next tree.
