Use mutexlock to replace critical section protection when using adc_isr_thread *Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* Summary The modification replaces critical section protection with mutex locks in ADC driver functions when CONFIG_ADC_ISR_THREAD is enabled, ensuring thread-safe hardware operations without unnecessarily disabling interrupts. Impact Benefits: Reduced Interrupt Latency: Interrupts remain enabled during hardware operations Better System Throughput: Other interrupts can still be serviced Improved Real-time Performance: Shorter critical sections mean better determinism Testing The ADC function was tested and verified to be working correctly using NuttX's built-in adc_drivers.（apps/examples/adc） Test Results： Test results: When you input adc -p in the nsh terminal, the pin corresponding to channel adc0 is shown below. [core2] adc -p [core2] adc_main:g_adcstate.count: 3 [core2] adc_main: Hardware initialized. Opening the ADC device: /dev/adc0 [core2] Sample: [core2] 1: channel: 32 value: 986 [core2] 2: channel: 34 value: 933 -- This is an automated message from the Apache Git Service.
