drivers: stm32: fix MSI PLL mode enabling

 1. clock: move the call for MSI hardware auto calibration enabling
    before the control of MSI enable to ensure its execution in all
    cases.
 2. counter: add call for MSI hardware auto calibration enabling after
    the LSE enabling and after possible backup domain reset that may
    clear MSIPLLEN.
