[PATCH v2 00/33] stm32: enable logging features

V2 of previous patchset [1],
I just rebase the serie and solved the compilation issue.

This patch-set migrates several stm32 drivers to API compatible with
logging features (use dev_...() or log_...() function) and activate
the logging features in STM32MP15 boards.

The size of U-Boot increased by 37kB (851096 to 889592 on STM32MP157C-EV1
board for trusted defconfig) but the boot time don't change drastically.

For example on STM32MP157C-EV1 board, trusted boot

1/ Before LOG patchset

STM32MP> bootstage report
Timer summary in microseconds (9 records):
       Mark    Elapsed  Stage
          0          0  reset
    621,283    621,283  board_init_f
    800,946    179,663  board_init_r
  1,272,726    471,780  id=64
  1,298,092     25,366  id=65
  1,299,997      1,905  main_loop
  1,310,785     10,788  id=175

Accumulated time:
                57,678  dm_f
                69,883  dm_r

After this serie :

STM32MP> bootstage report
Timer summary in microseconds (9 records):
       Mark    Elapsed  Stage
          0          0  reset
    626,031    626,031  board_init_f
    806,187    180,156  board_init_r
  1,280,935    474,748  id=64
  1,306,580     25,645  id=65
  1,308,484      1,904  main_loop
  1,319,262     10,778  id=175

Accumulated time:
                57,763  dm_f
                69,843  dm_r

=> cost 9ms

2/ With LOG activated at level 8
   and bootstage info in __log() function)

+ CONFIG_LOG_MAX_LEVEL=8
+ CONFIG_LOG_DEFAULT_LEVEL=6

STM32MP> bootstage report
Timer summary in microseconds (10 records):
       Mark    Elapsed  Stage
          0          0  reset
    641,076    641,076  board_init_f
    829,569    188,493  board_init_r
  1,339,783    510,214  id=64
  1,372,315     32,532  id=65
  1,374,182      1,867  main_loop
  1,544,359    170,177  id=175

Accumulated time:
                25,087  log
                63,300  dm_f
                73,424  dm_r

=> cost is 70ms

3/ after log patchset [2], I gain 20ms

STM32MP> bootstage report
Timer summary in microseconds (10 records):
       Mark    Elapsed  Stage
          0          0  reset
    644,372    644,372  board_init_f
    827,695    183,323  board_init_r
  1,323,756    496,061  id=64
  1,354,157     30,401  id=65
  1,356,050      1,893  main_loop
  1,366,785     10,735  id=175

Accumulated time:
                24,837  log
                59,676  dm_f
                70,916  dm_r

PS: accumulated time is strange here
