[PATCH v2] PCI: mediatek-gen3: Remove leftover mac_reset assert for Airoha EN7581 SoC.

[Krzysztof Wilczyński]

Hello,

> Remove a leftover assert for mac_reset line in mtk_pcie_en7581_power_up().
> This is not harmful since EN7581 does not requires mac_reset and
> mac_reset is not defined in EN7581 device tree.

Applied to controller/mediatek, thank you!
