[U-Boot] [PATCH v3 4/4] colibri_pxa270: transition to driver model for serial

[Marcel Ziswiler]

Add serial platform data to board file.
Enable driver model for PXA serial driver.

Signed-off-by: Marcel Ziswiler <marcel.ziswiler at toradex.com>

Changes in v3: None
Changes in v2:
- Drop baudrate checks.
- Use panic instead of just hang() to more gracefully handle
  failure case.
- Drop superfluous parenthesis around plat->base.
- Capitalise header file gating macro.
- Replace tab with space after #define.
