drm/radeon: Call radeon_suspend_kms() in radeon_pci_shutdown() for Loongson64
On the Loongson64 platform used with Radeon GPU, shutdown or reboot failed
when console=tty is in the boot cmdline.
radeon_suspend_kms() puts the hw in the suspend state, especially set fb
state as FBINFO_STATE_SUSPENDED:
if (fbcon) {
console_lock();
radeon_fbdev_set_suspend(rdev, 1);
console_unlock();
}
Then avoid to do any more fb operations in the related functions:
if (p->state != FBINFO_STATE_RUNNING)
return;
So call radeon_suspend_kms() in radeon_pci_shutdown() for Loongson64 to fix
this issue, it looks like some kind of workaround like powerpc.
