sensors/ina219: Fix voltage calculation
For voltage calculation wrong bit was tested to see if
range is 16 or 32V.
This could resulted in incorrect value being computed
depending if BRNG bit was matching bit from BG.
mcu/pic32: Add minimal boot code
There is special flash area dedicated to bootloader (0xbfc00000-0xbfc0FF00).
Code from this area is execute first.
This is where mcuboot is placed.
It is possible to build application elf that provides minimal
code that jumps to normal flash area dedicated for applications.
The elf generated this way can then easyly be used in MPLAB X ide
instead of command line gdb.
When syscfg has MCU_NO_BOOTLOADER_BUILD set to 1
additional section is generated that goes to bootloader area of MCU.
