Subject: [PATCH] USB: quirks: add USB_QUIRK_WINDOWS_CONFIG_REQ_SIZE for
 GameSir G7 SE

The GameSir G7 SE wired controller first enumerates as 3537:10a0 and
then re-enumerates in a mode it picks from how the host enumerated it.

When the configuration descriptor is fetched the Linux way, 9 bytes
followed by the full 80, the controller disconnects about 1 ms after
its string descriptors have been read, before SET_CONFIGURATION, and
comes back as 3537:1082, a generic HID gamepad without force feedback.

When the configuration descriptor is fetched in one 255-byte request,
as Windows does, it comes back as 3537:1010 in Xbox One (GIP) mode,
which xpad already supports, including rumble.

Skipping the device qualifier requests (USB_QUIRK_DEVICE_QUALIFIER)
makes no difference; the configuration descriptor request size alone
decides the mode. Add USB_QUIRK_WINDOWS_CONFIG_REQ_SIZE for the 10a0
identity, as is already done for the ShanWan Wireless Gamepad.
