drivers: rtc: stm32: remove ll in driver's file name

The `ll` part of driver's file name indicates that the implementation uses
the STM32Cube Low Level ("LL") library, which is not interesting because
there is only *one* STM32 driver implementation anyways. Addtionnally, the
presence of `ll` among STM32 drivers is not consistent.

Get rid of it for this class's driver to match most other STM32 drivers.
