Mateusz Szafoni 4c601faf6f Brings in initial WIP support for the STML0. This initial commit is in pretty bad shape and, hence it it marked EXPERIMENTAL."
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
