ACPI: EC: Handle IRQ storm on Acer laptops
On some Acer systems, the HW fails to clear the GPE source,
causing an interrupt storm.
So in EC interrupt mode, we count how many interrupts we
receive when waiting. If we get more than 5, we give
up on interrupt mode and revert to polling mode.
Also, for polling mode to work on Acers, we need
to insert a delay.
