Add the Samsung S3NRN4V NFC + eSE controller on i2c1. Its XI clock is
provided by the RF_CLK2 PMIC buffer and gated through the controller's
CLK_REQ line on tlmm GPIO6.
The enable line is routed to the chip's power-down input, which is
asserted high to turn the chip off (the downstream driver treats VEN as
active-low on this design) -- hence GPIO_ACTIVE_HIGH, unlike the
exynos5433-tm2 wiring of the same driver. The pin is pulled up so the
chip stays off while the line is not driven.
