Revert "t0lte: add NFC host-based card emulation"

Goddamnit, people are merging untested crap now.

All of the 4412 family have NXP (not Broadcom/NCI) NFC controllers, which don't actually support HCE.

GW will report that tap-to-pay is ready but it won't actually work.

This reverts commit 4854c06551e10bdcb3c23c429b00f1df1fb46052.
