PCI: mediatek-gen3: Avoid PCIe resetting via PERST# for Airoha EN7581 SoC
Airoha EN7581 has a hw bug asserting/releasing PERST# signal causing
occasional PCIe link down issues. In order to overcome the problem,
PERST# signal is not asserted/released during device probe or
suspend/resume phase and the PCIe block is reset using
en7523_reset_assert() and en7581_pci_enable().
Introduce flags field in the mtk_gen3_pcie_pdata struct in order to
specify per-SoC capabilities.
