[PATCH 5.17 080/225] ARM: dts: dra7: Fix suspend warning for vpe powerdomain

[Greg Kroah-Hartman]

From: Tony Lindgren <tony@xxxxxxxxxxx>

[ Upstream commit 8d2453d9a307c2eafd21242dd73f35f05fb7ce74 ]

We currently are getting the following warning after a system suspend:

Powerdomain (vpe_pwrdm) didn't enter target state 0

Looks like this is because the STANDBYMODE bit for SMART_IDLE should
not be used. The TRM "Table 12-348. VPE_SYSCONFIG" says that the value
for SMART_IDLE is "0x2: Same behavior as bit-field value of 0x1". But
if the SMART_IDLE value is used, PM_VPE_PWRSTST LASTPOWERSTATEENTERED
bits always show value of 3.

Let's fix the issue by dropping SMART_IDLE for vpe. And let's also add
the missing the powerdomain for vpe.
