Subject: sys-kernel/linux-{image,sources}-redcore-lts :

* version bump to v4.14.75
* adjust MuQSS v0.162 CPU scheduler to linux-hardened and enable it by default
* add BFQ-SQ v8r12 I/O scheduler and enable it by default
* lower HZ to 100 (recommended value for MuQSS enabled kernels)
* disable dynamic ticks (MuQSS itself is a tickless scheduler, so no longer required)
