For M.2 cards that rely on PCIe L2 link state and wake-up mechanisms, the card must remain powered during suspend. Patch 1 uses the existing dw_pcie_rp::skip_pwrctrl_off flag to skip power-off during suspend and skip power-on during the init path. Alsp the btnxpuart driver is extended to obtain a pwrseq descriptor via the OF graph on the UART controller device in patch 2.
