feat(spi_flash): implement dynamic CPU frequency switching workaround for encrypted writes
...
This commit implements a workaround that allows ESP32-C5 to run at 240MHz CPU frequency
normally, while automatically reducing CPU frequency during encrypted flash writes to
ensure correct operation. The frequency limit is chip revision dependent:
- v1.2 and above: limited to 160MHz during encrypted writes
- v1.0 and below: limited to 80MHz during encrypted writes
Key implementation details:
- Frequency limiting is triggered automatically when esp_flash_write_encrypted() is called
- Uses start() flags (ESP_FLASH_START_FLAG_LIMIT_CPU_FREQ) to integrate with OS layer
- Works with both PM enabled and disabled configurations
- Frequency is automatically restored after encrypted write completes
- For ESP32-C5 with 120MHz flash, Flash clock and timing registers are adjusted when
CPU frequency is reduced to 80MHz
- SPI1 timing registers are configured during frequency switching since encrypted writes
use SPI1 and must work correctly at reduced CPU frequencies
Code improvements:
- Use SOC_MSPI_FREQ_AXI_CONSTRAINED capability macro instead of hardcoded chip checks
- Control workaround via Kconfig (CONFIG_PM_WORKAROUND_FREQ_LIMIT_ENABLED) instead of
hardcoded macros
- Add comprehensive test cases covering various PM configurations and edge cases
This workaround enables ESP32-C5 applications to benefit from 240MHz CPU performance
while maintaining reliable encrypted flash write functionality.

test(esp_pm): add test case for USJ printing performance during wake-up
...
Add a new test case to verify that USJ printing doesn't block CPU on chip
wake-up from light sleep. The test measures the average time per print
operation and ensures it's below 5000 microseconds.
