[PATCH v2 2/4] ARM: dts: qcom: msm8974pro-htc-m8: add NFC support

[Alexandre Messier via B4 Relay]

From: Alexandre Messier <alex at me.ssier.org>

Add the NFC chip used in the HTC One M8 to its device tree.

The downstream vendor kernel used an I2C frequency of 384 kHz
for this bus. Use the same value as the vendor.
