It is not available on STM32H7

Hi there,
I used pyocd on STM32F4 and everything worked fine. When I tried to use pyocd on STM32H7, I had problems. I had read Docs.

Start by reproducing the reported pyocd pack -u command and review the documented STM32H7 setup mentioned in the issue. Trace the pack-update failure for Keil.STM32H7xx_DFP.pdsc; done means pyOCD can obtain the required pack and work with the STM32H7 as it does with the STM32F4.
