ramips: mt76x8: disable unused Ralink systick driver

Browse Source 
The mt76x8 series SoCs use the MIPS generic systick timer. Sync the
upstream Ralink systick driver changes and disable it for mt76x8
target to reduce the kernel size.

From 57cbfd333c9d65bfab1a06b49c75536ee28dc2ce Mon Sep 17 00:00:00 2001
From: Sergio Paracuellos <sergio.paracuellos@gmail.com>

Subject: clocksource/drivers/ralink: Add Ralink System Tick Counter driver
System Tick Counter is present on Ralink SoCs RT3352 and MT7620. This
driver has been in 'arch/mips/ralink' directory since the beggining of
Ralink architecture support. However, it can be moved into a more proper
place in 'drivers/clocksource'. Hence add it here adding also support for
compile test targets and reducing LOC in architecture code folder.
