arm64: dts: mediatek: mt8195: fix CPU IDLE synchronous aborts
This commit f7373aa8 ("Port DRM from CrOS TOT-246") has added support to DRM by porting many changes from CroS TOT-246. One of these changes caused the CLK_TOP_CLK26M_D2 clock to be turned off which is used by systimer. Doing this causes synchronous aborts when CPU IDLE is enabled. The issue is probably triggered when the kernel try to turn off all the unused clocks.
Reintroduce CLK_TOP_CLK26M_D2 clock for systimer in order to enable CPU IDLE again on mt8195.
