Improvements in STM32 ADC, minor changes in STM32 PWM, DMA, HRTIM and add some highpri ADC examples
arch/arch/src/stm32/stm32_adc: fix RCC reset logic
arch/arch/src/stm32/stm32_adc: move sample time change functions to low-level ADC ops
arch/arch/src/stm32/stm32_adc: configurable ADC DMA mode (one shot mode, circular mode)
arch/arch/src/stm32/stm32_pwm: remove llops_get interface. We can use structure casting to get pwm low-level ops
arch/arch/src/stm32/stm32_pwm: add timer enable/disable and frequency update to low-level ops
arch/src/arm/stm32: remove redundant stm32f33xxx_dma.c
arch/arm/src/stm32/stm32f40xxx_dma.c: add interfaces to interact with highp priority DMA interupts
arch/src/arm/stm32/stm32_hrtim: do not enable timers on startup if option from Kconfig selected and add interface to enable/disable timers
arch/src/arm/stm32/stm32_hrtim: fix some warnings
configs/nucleo-f334r8/highpri: update configuration due to changes in stm32_adc
configs/stm32f334-disco/buckboost: update configuration due to changes in stm32_adc
configs/nucleo-f334r8/highpri: add support for ADC injected sequence, add triggering from TIM1
configs/nucleo-f302r8/highpri: add high priority ADC interrupts example
configs/stm32f429i-disco/highpri: add high priority ADC interrupts example
