Subject: [PATCH v1 3/5] arm64: dts: rockchip: Add gpio-syscon10 to rk3328

From: Levin Du <djw@...hip.com.cn>

Adding a new gpio controller named "gpio-syscon10" to rk3328, providing
access to the pins defined in the syscon GRF_SOC_CON10.

Boards using these special pins to control regulators or LEDs, can now
utilize existing drivers like gpio-regulator and leds-gpio.

Signed-off-by: Levin Du <djw@...hip.com.cn>

Changes in v1:
- Split from V0 and add to rk3328.dtsi for general use.
