armv7/arm64: enable fifo in com_fdt for "snps,dw-apb-uart"

[Artturi Alm]

Hi,

does also remove ti,omapX-uart compatibles from arm64 com_fdt,
as they're never to be found there.
iirc. the lenght is based on minimal lenght i found from any datasheet
for SoCs w/"snps,dw-apb-uart", and conclusions drawn from gpl-sources.
