From: Amjad Ouled-Ameur <aouledameur@baylibre.com>

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.
