raiden00pl 60ddd837c7 !arch/arm/src/stm32: unify the timer input clock board options
Replace the divergent board conventions for the timer input clock
frequency with a single uniform convention provided by every board:

- STM32_APBx_TIMn_CLKIN and BOARD_TIMn_FREQUENCY -> STM32_TIMn_CLKIN
- STM32_APBx_LPTIMn_CLKIN, BOARD_LPTIMn_FREQUENCY and
  STM32_LPTIMn_FREQUENCY -> STM32_LPTIMn_CLKIN
- STM32_APB1_THRTIM1_CLKIN and BOARD_HRTIM1_FREQUENCY ->
  STM32_HRTIM1_CLKIN

All STM32 consumers (tim/lptim/pwm/adc/dac/capture/sdadc/dfsdm/
pulsecount) updated to match; the timer input clock is now bus-agnostic
in the drivers.

Boards that carried the same timer clock in more than one convention now
define STM32_TIMn_CLKIN exactly once, derived from the APB bus clock
(PCLKx with the x2 doubler when the APB prescaler is greater than 1),
instead of redefining it with a second, sometimes different, value.

BREAKING CHANGE: The timer input-clock board macros STM32_APBx_TIMn_CLKIN,
BOARD_TIMn_FREQUENCY, STM32_APBx_LPTIMn_CLKIN, BOARD_LPTIMn_FREQUENCY,
STM32_LPTIMn_FREQUENCY, STM32_APB1_THRTIM1_CLKIN and
BOARD_HRTIM1_FREQUENCY are removed in favor of STM32_TIMn_CLKIN,
STM32_LPTIMn_CLKIN and STM32_HRTIM1_CLKIN.  Out-of-tree boards must
define the new macros (drop the APB bus from the name, keep the value),
and out-of-tree drivers referencing the old names must be updated.
