Touchpad stops working after a few seconds in Lenovo ideapad 320

Bug description:
=== SRU Justifications ===
[Impact]
Touchpad freezes after a brief usage.
[Fix]
Quote from the commit log:
"The stale cached value written at the final stage undoes the masking.
Fix this by re-reading the register before clearing the interrupt.
I also spotted that the interrupt-clearing code can race against
amd_gpio_irq_mask() / amd_gpio_irq_unmask(), so add locking there.
Presumably this race was leading to the loss of interrupts."
[Test Case]
Touchpad no longer freezes on ideapad 320-15ABR, a new Dell Latitude and
a new Dell Inspiron.
[Regression Potential]
Low. It limits to AMD laptops
=== Original Bug Report ===
I have installed ubuntu bionic on a Lenovo ideapad 320. The touchpad
stops working a few seconds after I log in.
