arm64: dts: mediatek: mt8186-tentacruel: Fix touchscreen model

Browse source

[ Upstream commit 0370911565 ]

The touchscreen controller used with the original Krabby design is the
Elan eKTH6918, which is in the same family as eKTH6915, but supporting
a larger screen size with more sense lines.

OTOH, the touchscreen controller that actually shipped on the Tentacruel
devices is the Elan eKTH6A12NAY. A compatible string was added for it
specifically because it has different power sequencing timings.

Fix up the touchscreen nodes for both these. This also includes adding
a previously missing reset line. Also add "no-reset-on-power-off" since
the power is always on, and putting it in reset would consume more
power.
