MT8365 has a SYST timer (System Timer), therefore the compatible node
should be "mediatek,mt6765-timer" instead of "mediatek,mt6795-systimer"
(which corresponds to ARM/ARM64 System Timer).

Plus, register range should be 0x100 instead of 0x10.

Finally, interrupt polarity of systimer is LEVEL_HIGH.

Fix the above properties accordingly.

Patch looks good but does not apply cleanly because of previous patches that I didn't take and need rework. Please resend the patches I didn't queue with the comments addressed.

Regards,
Matthias
