[PATCH v2 2/2] udoo_neo: Select DM_SERIAL and drop iomux board level init

[Peter Robinson <pbrobinson@gmail.com>]

Convert to DM_SERIAL and drop the iomux board file
level init as it's handled as part of the DM serial
layer instead.

Signed-off-by: Peter Robinson <pbrobinson@gmail.com>

Changes in v2:
- Drop no longer needed setup_iomux_uart and associated bits
