This patch adds PM support to UART driver for the TI cc23x0 SoC.

Datasheet: https://www.ti.com/lit/ds/symlink/cc2340r5.pdf

Another PR, introducing system PM for this SoC, must be merged before: #91401

Let's remind that this peripheral may use DMA. A PR is submitted to add PM support in DMA driver: #92219

[NOTE] Following the discussion about PM for DMA driver, this PR will be updated soon: pm_device_runtime_get/put(dma_dev) will be introduced to follow this implementation.

Add PM support to cc23x0 UART module.

Hi @dcpleung AFAICS you're still alone for reviewing this PR. Do you know somebody who could be added to review it ?

Maybe post on #pr-help in discord to see if anyone else are interested?
