[PATCH 10/11] mfd: stm32-timers: remove dependency of mfd/stm32-timers.h on regmap.h

[Ahmad Fatoum]

Drivers for the STM32 timer MFD and the PWM within it used regmap API
without directly including the regmap.h header. Fix that and replace
the regmap.h inclusion in mfd/stm32-timers.h with a forward declaration.
