[PATCH v2] dt-bindings: clock: agilex: mark mpu_l2ram_clk deprecated

[genevieve . chan]

From: Genevieve Chan <genevieve.chan@xxxxxxxxxx>

Preliminary documentation referred to mpu_l2ram_clk, but that clock is
now mpu_ccu_clk and is already represented by AGILEX_MPU_CCU_CLK.
Keep AGILEX_MPU_L2RAM_CLK as a legacy ABI-preserved ID (do not use in
new DTs).

Fixes: 6b3c59780ed3 ("dt-bindings: documentation: add clock bindings information for Agilex")
Cc: stable@xxxxxxxxxxxxxxx # 5.8+
