27bc12de61 stm32: unify bulk of adc convenience functions
This unifies stm32f1, l1, and f4 convenience functions for adc.  The code
should be useable for f2 and f37x as well, but that needs hardware for testing,
and there was no existing implementation. This is the reason for the
"adc_common_v1.c" name, as trying to put all the different families into the
common file name has become too cumbersome.

All of the deprecated routines have been dropped, they've been marked
deprecated for a very long time now, and porting them seemed unnecessary.

This has been tested on f1, l1 and f4 discovery boards, and is based on some
existing l1/f1 unification code from

6570f6eb07 Fix the order of ADC injected channel list
According to RM0090, page 301, paragraph 11.13.12 Note. (For F4, for F1 and F3 is it in the corresponding manuals)

The JSQR are filled always ending at SQR4 ie for those lists we must set this list:

(A)       ->                               JSQ4 = A,
(A,B)     ->                     JSQ3 = A, JSQ4 = B,
(A,B,C)   ->           JSQ2 = A, JSQ3 = B, JSQ4 = C,
(A,B,C,D) -> JSQ1 = A, JSQ2 = B, JSQ3 = C, JSQ4 = D,

The readed values are in correct order, starting from JDR1:

(A)       -> JDR1 = A,
(A,B)     -> JDR1 = A, JDR2 = B,
(A,B,C)   -> JDR1 = A, JDR2 = B, JDR3 = C,
(A,B,C,D) -> JDR1 = A, JDR2 = B, JDR3 = C, JDR4 = D,

bbde1012a3 stm32/f4/adc: Fix set_resolution
I can only imagine the resolution argument was 16 bits due to some cut
and paste error

7df63fcae0 First coarse run to fix coding style in locm3.
Added --terse and --mailback options to the make stylecheck target. It
also does continue even if it enounters a possible error.

We decided on two exceptions from the linux kernel coding standard:
- Empty wait while loops may end with ; on the same line.
- All blocks after while, if, for have to be in brackets even if they
  only contain one statement. Otherwise it is easy to introduce an
  error.

Checkpatch needs to be adapted to reflect those changes.

08a14a9d9e stm32/f4/adc: DMA can always be used with ADC2
I can't find any evidence in the manual to support this comment's claim.

0bd415365d STM32F4: New adc module
Note adc.h was provided by Matthew Lai but was never merged.
adc.c is new.
