west.yml: use latest STM32 HAL to get PTP to work

In the HAL_ETH_ReadData function where it checks for the last
descriptor, I added a checked if the TSA bit was set in DESC1
If the TSA bit is set then have a peak at the context descriptor
which should be the one after the last descriptor
If the CTXT bit is set in the context descriptor then extract
the timestamps
