[U-Boot] [PATCH v2 01/18] dm: ns16550: Support CONFIG_SYS_NS16550_MEM32 with driver model

[Simon Glass]

This option is used by some boards, so support it with driver model. This
is really ugly - we should rewrite this driver once all users are moved to
driver model.

Changes in v2:
- Simplify the support for CONFIG_SYS_NS16550_MEM32
