Add RTD1315E support using realtek common pinctrl driver.

...

+config PINCTRL_RTD1315E
+	tristate "Realtek DHC 1315E pin controller driver"

+	depends on PINCTRL_RTD

Why not select and the above be hidden symbol?

...

+#include <linux/module.h>

+#include <linux/of.h>

Not used. Use correct headers

+#include <linux/platform_device.h>

+ Blank line

+#include <linux/pinctrl/pinctrl.h>

Make use of struct pinconfig, struct pinfunction and respective PINCTRL_PIN*()
macros.

...

+#define RTD1315E_GROUP(_name) \
+	{ \
+		.name = # _name, \
+		.pins = rtd1315e_ ## _name ## _pins, \
+		.num_pins = ARRAY_SIZE(rtd1315e_ ## _name ## _pins), \
+	}

NIH PINCTRL_PINGROUP().

+		.num_groups = ARRAY_SIZE(rtd1315e_ ## _name ## _groups), \
+	}

NIH PINCTRL_PINFUNCTION().

...

+static const struct of_device_id rtd1315e_pinctrl_of_match[] = {
+	{ .compatible = "realtek,rtd13xxe-pinctrl", },

+	{},

No comma for the terminator entry.

+};

...

Same comments for all new drivers in the series.
