Squashed commit of the following:
arch/arm/src/stm32f0l0: Various changes for a clean compilation. Still does not compile correctly due to missing FLASH latency definitions.
arch/arm/src/stm32f0l0/hardware: Add framework for the STM32 L0. Currently set to same as the STM32F0.
arch/arm/src/stm32f0l0/hardware: Very fragmentary FLASH header register definitions for the STM32 L0.
arch/arm/src/stm32f0l0: Bring in DMA v1. Cannot possibly be functionaly yet due to the limited number for M0 interrupts.
arch/arm/src/stm32f0l0: Add STM32 F0/L0 LSE and backup power domain controls.
arch/arm/src/stm32f0l0/hardware/stm32l0_pwr.h: Add STM32L0 PWR header file.
arch/arm/include/stm32f0l0/chip.h: Clean up WIP chip header file.
arch/arm/include/stm32f0l0/chip.h: WIP.
arm/src/stm32f0l0: Resolve some small differences between F0 and L0 GPIO pin options.
arch/arm/src/stm32f0l0: Better integrate STM32L0 header files.
nuttx/arch/arm/include/stm32f0l0: Add STM32L0 IRQ number definition file.
arch/arm/src/stm32f0l0: Add STM32L0 RCC driver.
arch/arm/src/stm32f0l0/hardware: Adds basic STM32L0 header files.
arch/arm/src/stm32f0l0: Add STM32L0 chip selections.
configs/: Hook new STM32L0 boards into the configuration system.
configs: nucleo boards use as default ST LINK MCO as clock input from MCU and for this HSEBYP must be enabled
configs: add basic support for nucleo-l073rz
configs: add basic support for b-l072z-lrwan1
configs/nucleo-f207zg, configs/nucleo-f103rb: add ADC and PWM examples; arch/arm/src/stm32_adc.c: there is no DMA CFG bit for the basic IPv1 ADC

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
