drm/amdgpu: Adjust removal control flow for smu v13_0_2

Adjust removal control flow for smu v13_0_2:
   During amdgpu uninstallation, when removing the first
device, the kernel needs to first send a mode1reset message
to all gpu devices. Otherwise, smu initialization will fail
the next time amdgpu is installed.

V2:
1. Update commit comments.
2. Remove the global variable amdgpu_device_remove_cnt
   and add a variable to the structure amdgpu_hive_info.
3. Use hive to detect the first removed device instead of
   a global variable.

V3:
 1. Update commit comments.
 2. Split a patch into multiple patches.
 3. The current patch does:
    a. Add a work mode of AMDGPU_RESET_FOR_DEVICE_REMOVE into
       the existing gpu recover path, which make all devices
       in hive list only have HW reset but no resume (except
       the base IP).
    b. Call AMDGPU_RESET_FOR_DEVICE_REMOVE and
       AMDGPU_NEED_FULL_RESET mode of amdgpu_device_gpu_recover
       in amdgpu_pci_remove when removing the first device in
       hive list.
    c. When removing the first device, the IP blocks keyword
       function call sequence is as follows:
.suspend->mode1reset->.resume(basic ip)->.hw_fini->.early_fini->.sw_fini.
   ^                           |
   |-<----------<---------<----|
	The first three sequences are because of a call to
        amdgpu_device_gpu_recover. The three sequences will be
        executed in a loop until all devices in the hive list
        are iterated.
        The sequences starting from .hw_fini only apply to the
        first device. Since .suspend has been called before,
        except the resumed phase1 basic ip blocks, all other ip
        blocks .hw_fini of current device will do nothing.
     d. When removing other devices, the calling sequences is the
        same as legacy:
	   .hw_fini -> .early_fini -> .sw_fini.
	Since .suspend has been called when removing the first device,
        except the resumed phase1 basic ip blocks, all of other ip
        blocks .hw_fini of current device will do nothing.
