U-Boot 2024.07 drops on aristainetos2 board the following warning:

Failed to enable per_clk

and bootlogo is not seen on LVDS display.

This patch uses old behaviour for systems without clock framework if CONFIG_CLK is not enabled.

Fixes: bfc778cb93a3 ("driver: pwm: pwm-imx: get and enable per/ipg clock using dm")
