Add macro and dependency to avoid boilerplate code. Since now simple
i2c drivers only have to include the i2c.h header and call the
device_i2c_driver() macro to register a i2c device driver.

Adds support to the driver to enable VBAT regulator at init time.
This is similar to ba14301e0356 ("fbdev/ssd1307fb: add support to enable
VBAT") and cfc5b2b551d8 ("fbdev/ssd1307fb: fix optional VBAT support")
in Linux kernel.

It was ported from linux v4.10. Like the kernel driver only
communication via I2C is supported.
It has only been tested with a SSD1306 and a 96x16 OLED display:
&i2c0 {
status = "okay";
ssd1306: oled@3c {
compatible = "solomon,ssd1306fb-i2c";
reg = <0x3c>;
reset-gpios = <&gpio1 1 0>;
solomon,height = <16>;
solomon,width = <96>;
solomon,page-offset = <0>;
solomon,com-invdir;
solomon,com-seq;
};
