[PATCH v4 0/2] Enable audio on lemans-evk board

[Mohammad Rafi Shaik]

Enable audio support on lemans-evk board.

Introduce HS (High-Speed) MI2S pin control support.
The I2S max98357a speaker amplifier is connected via HS0 and I2S
microphones utilize the HS2 interface.

DT-Binding link for sound compatible:

changes in [v4]:
	- Nodes sorted in the proper order reported by Konrad Dybcio.
	- Since the base SoC device tree Renamed from sa8775p.dtsi to lemans.dtsi, and
	  the board-specific device tree from qcs9075-iq-9075-evk.dts to lemans-evk.dts,
	  moved audio support device tree nodes to the new lemans device tree.
	  Renamed device tree reference Link: https://lore.kernel.org/all/20250803110113.401927-1-wasim.nazir@oss.qualcomm.com/

changes in [v3]:
	- Updated link-name from HS0 MI2S to HS1 MI2S and sorted nodes in order.
	- Link to V2 : https://lore.kernel.org/linux-arm-msm/20250616070405.4113564-1-mohammad.rafi.shaik@oss.qualcomm.com/

changes in [v2]:
	- Updated commit message as suggested by Dmitry Baryshkov.
