USB Interrupt Priority and CRS Configuration for STM32L433

This PR implements proper USB interrupt priority configuration and Clock Recovery System (CRS) setup for the STM32L433-based Cygnet board:

  1. Sets USB interrupt priority to 1 for STM32L433
  2. Lowers HAL tick interrupt priority to 2 to ensure proper USB operation
  3. Adds CRS configuration for HSI48 clock to maintain USB clock synchronization

These changes should improve USB stability and reliability on the Cygnet board by:

  • Ensuring USB interrupts have higher priority than system tick
  • Maintaining proper USB clock synchronization via CRS
  • Following STM32L4 best practices for USB configuration

Testing

  • Built successfully for STM32L433
  • Physical device testing needed to verify USB enumeration and stability

stm32l4: Add USB suspend/resume power management for STM32L433
d754c51 
Implements board-level power management hooks for USB suspend/resume on the
STM32L433-based Cygnet board. This includes:

- USB interrupt priority configuration
- Power management implementation for suspend/resume
- GPIO clock management during low power states
- System clock reconfiguration after wake from STOP mode

Part of the USB functionality improvements for the Cygnet board.
