lack of board.h file, unset this on the slimbootloader platform and remove
the otherwise empty file.

Slim Bootloader provides serial port info in its HOB to support
both IO or MMIO serial ports, but it's controlled by SYS_NS16550_MEM32
or SYS_NS16550_PORT_MAPPED in U-Boot.
To support both serial port configurations dynamically at runtime,
Slim Bootloader serial driver leverages NS16550_DYNAMIC.
