drm/amd/display: Use VUPDATE_NO_LOCK instead of VUPDATE for dcn30

[Why]
Soft hangs occur when FreeSync is engaged since we utilize VUPDATE
(which doesn't fire when holding the pipe lock) to send back vblank

The alternative (working) interrupt source for this mechanism is
VUPDATE_NO_LOCK. We already use this all other DCN revisions so align
dcn30 with those as well.

gpu/drm: Remove debug info about CPU address

When I update the latest kernel, I see the following "____ptrval____" boot
messages.

[    1.872600] radeon 0000:01:05.0: fence driver on ring 0 use gpu addr 0x0000000048000c00 and cpu addr 0x(____ptrval____)

Both radeon_fence_driver_start_ring() and amdgpu_fence_driver_start_ring()
have the similar issue, there exists the following two methods to solve it:
(1) Use "%pK" instead of "%p" so that the CPU address can be printed when
the kptr_restrict sysctl is set to 1.
(2) Just completely drop the CPU address suggested by Christian, because
the CPU address was useful in the past, but isn't any more. We now have a
debugfs file to read the current fence values.

Since the CPU address is not much useful, just remove the debug info about
CPU address.

drm/amd/display: Only revalidate bandwidth on medium and fast updates

[Why]
Changes that are fast don't require updating DLG parameters making
this call unnecessary. Considering this is an expensive call it should
not be done on every flip.

DML touches clocks, p-state support, DLG params and a few other DC
internal flags and these aren't expected during fast. A hang has been
reported with this change when called on every flip which suggests that
modifying these fields is not recommended behavior on fast updates.

[How]
Guard the validation to only happen if update type isn't FAST.

drm/amdkfd: Update hardware scheduling time quanta

Update PROCESS_QUANTUM, the time the hardware scheduler allows

Error appears when some i2c device driver tries to probe for devices
using adapter registered by `smu_v11_0_i2c_eeprom_control_init()`.
Code supporting this adapter requires `adev->psp.ras.ras` to be not
NULL, which is true only when `amdgpu_ras_init()` detects HW support by
calling `amdgpu_ras_check_supported()`.

Before 9015d60c9ee1, adapter was registered by

-> amdgpu_device_ip_init()
  -> amdgpu_ras_recovery_init()
    -> amdgpu_ras_eeprom_init()
      -> smu_v11_0_i2c_eeprom_control_init()

after verifying that `adev->psp.ras.ras` is not NULL in
`amdgpu_ras_recovery_init()`. Currently it is registered
unconditionally by

-> amdgpu_device_ip_init()
  -> pp_sw_init()
    -> hwmgr_sw_init()
      -> vega20_smu_init()
        -> smu_v11_0_i2c_eeprom_control_init()

Fix simply adds HW support check (ras == NULL => no support) before
calling `smu_v11_0_i2c_eeprom_control_{init,fini}()`.

Please note that there is a chance that similar fix is also required for
CHIP_ARCTURUS. I do not know whether any actual Arcturus hardware without
RAS exist, and whether calling `smu_i2c_eeprom_init()` makes any sense
when there is no HW support.

ret is never set to an error condition and the function returns
