[LEDE-DEV] [PATCH] mt7621: Add back CONFIG_SCHED_HRTICK to kernel config

[Rosen Penev]

Fixes FS #1242.

The way I figured this out was by using diff on config-4.4 from 17.01
and config-4.9 from trunk. First I removed CONFIG options. That did not work.
Then I started adding. This one seems to do the trick.

The issue is that anything in /dev/sdX starts returning bad data when read.
PCIe or USB does not matter. I have not tested NVME since I lack the hardware.
/dev/mtdblockX may or may not be impacted. No idea.
