Subject: nfit-test: Add platform cap support from ACPI 6.2a to test
Patch-mainline: v4.16-rc1
Git-commit: f81e1d35a6e36d30888c46283b8dd1022e847124
References: bsc#1091424

Adding NFIT platform capabilities sub table in nfit_test simulated ACPI
NFIT table. Only the first NFIT table is added with the capability
sub-table.
