The variable `pm_suspend_target_state` is conditionally defined only when
`CONFIG_SUSPEND` is enabled (see `include/linux/suspend.h`). Directly
referencing it without guarding by `#ifdef CONFIG_SUSPEND` causes build
failures when suspend functionality is disabled (e.g., `CONFIG_SUSPEND=n`).

Previously we tried to keep the HW specific PTE flags in each mapping,
but for CRIU that isn't sufficient any more since the original value is
needed for the checkpoint procedure.
So rework the whole handling, nuke the early mapping function, keep the
UAPI flags in each mapping instead of the HW flags and translate them to
the HW flags while filling in the PTEs.
Only tested on Navi 23 for now, so probably needs quite a bit of more
work.

[WHY]
If symclk RCO is enabled, stream encoder may not be receiving an ungated
clock by the time we attempt to set stream attributes when setting dpms
on. Since the clock is gated, register writes to the stream encoder fail.
[HOW]
Move set_stream_attribute call into enable_stream, just after the point
where symclk32_se is ungated.
Logically there is no need to set stream attributes as early as is
currently done in link_set_dpms_on, so this should have no impact beyond
the RCO fix.
