drivers: usb: udc: stm32: use instance MPS for IN endpoints capabilities

mathieuchopstm · cfriedt · commit 2e998cf17daa · 2025-10-31T10:22:29.000-04:00
When setting endpoint capabilities, the driver uses the MPS stored in each
instance's configuration for OUT endpoints, but used a hardcoded 1023 for
IN endpoints.

Use the instance MPS when preparing IN endpoints' capabilities too.
