Minghao Chi f359c3e579 mfd: stm32-lptimer: Use devm_platform_get_and_ioremap_resource()
Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

Benjamin Gaignard 45d93065c8 mfd: stm32: Enable regmap fast_io for stm32-lptimer
Because stm32-lptimer need to write in registers in interrupt context
enable regmap fast_io to use a spin_lock to protect registers access
rather than a mutex.

Fabrice Gasnier e8924005b4 mfd: Add STM32 LPTimer driver
STM32 Low-Power Timer hardware block can be used for:
- PWM generation
- IIO trigger (in sync with PWM)
- IIO quadrature encoder counter
PWM and IIO timer configuration are mixed in the same registers so
we need a multi fonction driver to be able to share those registers.
