Subject: [PATCH v8 20/22] wifi: nxpwifi: add NXP vendor and IW61x device IDs to sdio_ids.h

Register NXP's SDIO vendor ID (0x0471) and IW61x device ID (0x0205)
in the global SDIO ID list. This allows the nxpwifi SDIO driver to
match and bind to supported NXP Wi-Fi chips via the SDIO bus.

+      from sleep. This property is only necessary if the wakeup pin is
+      wired in a non-standard way, such that the default pin assignments
+      are invalid.
