[efi] Do not raise TPL within EFI_DRIVER_BINDING_PROTOCOL.Supported()
When booting some versions of the UEFI shell, our driver binding
protocol's Supported() entry point is called at TPL_NOTIFY for no
discernible reason. Attempting to raise to TPL_CALLBACK triggers an
immediate assertion failure in the firmware.
Since our Supported() method can run at any TPL, fix by simply not
attempting to raise the TPL within this method.
