## Summary
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`
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` and
`STM32_LPTIMn_FREQUENCY` are removed in favor of `STM32_TIMn_CLKIN` and
`STM32_LPTIMn_CLKIN`. Out-of-tree boards must define `STM32_TIMn_CLKIN` /
`STM32_LPTIMn_CLKIN` (drop the APB bus from the name, keep the value), and
out-of-tree drivers referencing the old names must be updated.
## Impact
unification of the last greatest divergence between STM32 ports.
