NFC: nxp-nci: Clarify on supported chips

This patch clarifies on the supported NXP NCI chips and families
and lists PN547 and PN548 separately which are known as NPC100
respectively NPC300.

This helps to find informations and identify drivers on vendor's
support websites.

For details see the discussion in [1] and [2].
