Subject: [PATCHv2] x86: Removing invalid reference to Intel CPUs in CONFIG_SWIOTLB

Deleted the no longer valid example of which x86 CPUs lack a hardware
IOMMU, and moved the "If unsure..." statement to a new line to follow
the style of surrounding options.

v2: Incorporated feedback from Konrad Rzeszutek Wilk that no mention of
    Intel CPUs was needed.
