nfc: pn532: Add uart phy docs and rename it

This adds documentation about the uart phy to the pn532 binding doc. As
the filename "pn533-i2c.txt" is not appropriate any more, rename it to
the more general "pn532.txt".
This also documents the deprecation of the compatible strings ending
with "...-i2c".

-* NXP Semiconductors PN532 NFC Controller
-
-Required properties:
-- compatible: Should be "nxp,pn532-i2c" or "nxp,pn533-i2c".
-- clock-frequency: I²C work frequency.
-- reg: address on the bus
-- interrupts: GPIO interrupt to which the chip is connected
-
-Optional SoC Specific Properties:
-- pinctrl-names: Contains only one value - "default".
-- pintctrl-0: Specifies the pin control groups used for this controller.
-
-Example (for ARM-based BeagleBone with PN532 on I2C2):
-
-&i2c2 {
-
-
-	pn532: pn532@24 {
-
-		compatible = "nxp,pn532-i2c";
-
-		reg = <0x24>;
-		clock-frequency = <400000>;
-
-		interrupt-parent = <&gpio1>;
-		interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
-
-	};
