In IRQ handler, ONLY clock enable/disable is called due to clock prepare can NOT be called in interrupt context, but clock enable/disable will return failure if prepare count is 0, to fix this issue, just make SNVS clock always prepared there, the SNVS clock has no prepare function implemented, so it won't impact anything.
