input: remove PM QoS latency request

Samsung sets QoS latency to zero, which disables all CPU idle functions
on input, causing high power usage, specially when Exynos 9810's M3 cores
power usage isn't friendly at all

To avoid touch latency, we'll adapt another method that significantly
improves IRQ behaviours
