clk: qcom: lahaina: Fix providers left active in suspend

The PM framework prevents runtime_suspend() callbacks after
device_prepare() is called by calling pm_runtime_get_noresume(), which
increments the usage_count. If consumers don't disable their clocks
until after device_prepare(), then the clock provider will remain active
since usage_count=1. This results in regulator votes persisting after
suspend, which blocks system low power modes.

Register for the standard pm_runtime_force_suspend() and
pm_runtime_force_resume() callbacks, which force the device into suspend
even if usage_count=1. Register them in suspend_late, since consumer
clock votes will be removed earlier in suspend.
