[PATCH v2] arm64: dts: qcom: ipq5424: fix and relocate uart1 gpio configurations

[Manikanta Mylavarapu <quic_mmanikan@xxxxxxxxxxx>]

Update the bias configuration for UART1 TX and RX pins to ensure correct
settings for RDP466.

Additionally, move the UART1 GPIO configurations from the common .dtsi
file to the RDP-specific .dts files to account for differing bias
configurations across RDPs of IPQ5424.

Fixes: 1a91d2a6021e ("arm64: dts: qcom: add IPQ5424 SoC and rdp466 board support")

Changes in V2:
	- Consolidated uart1_tx_state and uart1_rx_state nodes into a
	  single qup_uart1_default_state node, which includes the
	  configuration for both UART1 TX and RX pins.
	- Inserted a blank line before the status property in the UART1
	  node.
	- Fixed review comments from Kathiravan Thirumoorthy.
