[PATCH] arm64: dts: mediatek: mt8186-corsola: Fix GPU supply coupling max-spread

[Chen-Yu Tsai]

The GPU SRAM supply is supposed to be always at least 0.1V higher than
the GPU supply. However when the DT was upstreamed, the spread was
incorrectly set to 0.01V.

Fixes: 8855d01fb81f ("arm64: dts: mediatek: Add MT8186 Krabby platform based Tentacruel / Tentacool")

Noticed this while trying to align the downstream Mali driver to the
upstream device tree and binding.
