Deferred driver probing shouldn't result in errors or warnings being logged,
because their presence in the kernel log provides no value and may actually
cause false impression that some issues exist.  Thus, let's no longer produce
error messages when getting the dphy results in deferred probing.

This prevents misleading error messages like the following one, which was
observed on a Pine64 PineTab2, from appearing in the kernel log.  To make
matters worse, the following error message was observed appearing multiple
times in the kernel log of a single PineTab2 boot:

  dw-mipi-dsi-rockchip fe060000.dsi: [drm:dw_mipi_dsi_rockchip_probe \
  [rockchipdrm]] *ERROR* failed to get mipi dphy: -517

At the same time, make the adjusted logged message a bit more consistent with
the other logged messages by capitalizing its first word.
