I added one patch to this same PR, just found a bug that it was not possible to re-start the PWM outputs if it had been stopped. |

Summary
This adds an LPTPM timer based PWM control to IMX9 platform. On i.MX93 there are 6 TPM modules with 4 timers each.
In addition, this configures one PWM output on imx93-evk board's 40 pin header (GPIO_IO24).
Impact
Affects only IMX9 based designs
Testing
Some of the channels of TPM1, TPM3 and TPM4 modules have been tested on EVK pins. All can't be tested on the EVK board.
