No SFR files in STM32U5xx_DFP 3.1.0 and 3.1.1

This has only been tested with MDK 5.43a

Problem exist with STM32U5xx_DFP v3.1.0 and v3.1.1 but not with v3.0.0

With v3.0.0 SFR files are included in subfolder STM32U5xx_DFP\3.0.0\CMSIS\SVD

But with v3.1.0 and 3.1.1 only SVD files are included

This results in peripheral registers not showing up while debugging with uVision.

A workaround is to generate the SFR files manually, but it should not be necessary to begin with.
