According to the documentation, drivers are responsible for undoing at
removal time all runtime PM changes done during probing.
Hence, add the missing calls to pm_runtime_dont_use_autosuspend(), which
are necessary for undoing pm_runtime_use_autosuspend().

The interrupt handler invokes pm_runtime_get_sync() without checking the
returned error code.
Add a proper verification and switch to pm_runtime_resume_and_get(), to
avoid the need to call pm_runtime_put_noidle() for decrementing the PM
usage counter before returning from the error condition.

Enabling the active/passive shared boosts requires setting SYNC_EN, but
*not* before receiving the PLL Lock signal.
Due to improper error handling, it was not obvious that waiting for the
completion operation times out and, consequently, the shared boost is
never activated.

Technically, an interrupt handler can be called before probe() finishes
its execution, hence ensure the pll_lock completion object is always
initialized before being accessed in cs35l41_irq().
