ARM: AM43xx: clk: Add a comment for not using "clk_rc32k_ck"

The On-Chip 32K RC Osc clock is not an accurate clock-source as per the design/spec. So try not to use this as a clock source. For now adding a comment is helpful for others using this as a clocksource. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
