Subject: [PATCH v2 2/9] arm64: dts: renesas: r9a09g077m44-rzt2h-evk: Add user LEDs

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Add USER LED0-LED8, which are available on RZ/T2H EVK.

In addition, the header file inclusion has been moved into the common
rzt2h-n2h-evk-common.dtsi so that both RZ/T2H and RZ/N2H EVK DTS/I files
share the same set of bindings. This avoids duplication and keeps the
board files consistent.

Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>
---
v1->v2:
- Changed led node names
- Added color/function/function-enumerator properties
- Replaced GPIO_ACTIVE_LOW with GPIO_ACTIVE_HIGH
- Moved header file inclusions to common dtsi
