CAN IDs.
* arch/arm/src/lpc17xx/lpc17_can.c: Add support for extended (29-bit) CAN IDs.
* arch/arm/src/stm32/stm32_can.c: Add support for extended (29-bit) CAN IDs.
* include/nuttx/power/pm.h: Move include/nuttx/pm.h into a sub-directory named
power.
* drivers/power: Rename the drivers/pm directory to power
* drivers/power/max1704x.c: Add a skeleton file that will eventually become
the MAX17040x battery driver.
