Merge branch 'nfc-constify-pointed-data-missed-part' 

Krzysztof Kozlowski says:

====================
nfc: constify pointed data - missed part

This was previously sent [1] but got lost. It was a prerequisite to part two of NFC const [2].

Changes since v2:
1. Drop patch previously 7/8 which cases new warnings "warning: Using
   plain integer as NULL pointer".

Changes since v1:
1. Add patch 1/8 fixing up nfcmrvl_spi_parse_dt()
