  Add bindings for TI TMAG5273.

Signed-off-by: Gerald Loacker <gerald.loacker@wolfvision.net>
---
Changes in v2:
 - Removed nodename
 - Changed angle-enable to angle-measurement and used strings
 - Added interrupts
 - Removed vcc-supply from required properties
 - Changed i2c-0 to i2c in examples

+description:
+  The TI TMAG5273 is a low-power linear 3D Hall-effect sensor. This device
+  integrates three independent Hall-effect sensors in the X, Y, and Z axes.
+  The device has an integrated temperature sensor available. The TMAG5273
+  can be configured through the I2C interface to enable any combination of
+  magnetic axes and temperature measurements. An integrated angle calculation
+  engine (CORDIC) provides full 360° angular position information for both
+  on-axis and off-axis angle measurement topologies. The angle calculation is
+  performed using two user-selected magnetic axes.
