The rf2xx driver needs GPIO driver to works. The RST, SLPTR and INT
are mandatory signals and driver uses DT to configure them. This add
the GPIO dependency on Kconfig.rf2xx file.

Same deal as in commit bd6e04411e ("kconfig: Clean up header comments
and make them consistent") and commit 1f38ea77ba ("kconfig: Clean up
'config FOO' (two spaces) definitions"), for some newly-introduced
stuff.

Add initial Atmel at86rf2xx transceiver driver. This driver uses device
tree to configure the physical interface. The driver had capability to
use multiple transceiver and systems with multiple bands can be used.
With this, 2.4GHz ISM and Sub-Giga can be used simultaneous.
Below a valid DT example. This samples assume same SPI port with two
transceivers.
&spi0 {
status = "okay";
label = "SPI_RF2XX";
cs-gpios = <&porta 31 0 &porta 30 0>;
rf2xx@0 {
compatible = "atmel,rf2xx";
reg = <0x0>;
label = "RF2XX_0";
spi-max-frequency = <7800000>;
irq-gpios = <&portb 2 0>;
reset-gpios = <&porta 3 0>;
slptr-gpios = <&portb 3 0>;
status = "okay";
};
rf2xx@1 {
compatible = "atmel,rf2xx";
reg = <0x1>;
label = "RF2XX_1";
spi-max-frequency = <7800000>;
irq-gpios = <&portb 4 0>;
reset-gpios = <&porta 4 0>;
slptr-gpios = <&portb 4 0>;
status = "okay";
};
};
At the moment driver assume two transceiver are enouth for majority of
appications. Sub-Giga band will be enabled in future.
