Now that the big pieces of the adc-v2 common files are in place, start
including l0 in the builds. This includes only the very very basic core v2
peripheral functions, and the very basic definitions.
As done by esden for the F4, remove typedefs and add prefixes to clock enums
This extends this to all stm32 families.
Let's not hide the fact that these variables are structs/enums.
We are filling up the namespace badly enough, we should be prefixing as
much as we can with the module names at least. As users we already run
often enough in namespace colisions we don't have to make it worse.
* CLOCK_3V3_xxx enums renamed to RCC_CLOCK_3V3_xxx
* clock enums (PLL, HSI, HSE ...) prefixed with RCC_
* scale enum of pwr module prefixed with PWR_
Renamed every instance of variable CFLAGS in target specific Makefiles
to TGT_CFLAGS to free up CFLAGS for user defined compiler flags.
Added information in README.md about existence and usage of CFLAGS
environment variable in build process.
-ggdb3 make slightly bigger .elf files, but allows gdb to understand
macros, which libopenocm3 uses somewhat extensively. Make this the
default, and pull it up to the common base makefile, so it can be easily
substituted.
Tested with a miniblink example on the l053 discovery board.
Only register definitions at this stage, no helpers.
Register definitions from RM0367r2, hopefully the biggest
superset of L0 parts.

Committed to binutils back in 2012, so even though it has no real impact, it at
least does the right thing for future compilers to make better decisions.
