commit 5706cb3c910cc8283f344bc37a889a8d523a2c6d upstream.

'pm_suspend_target_state' is only available when CONFIG_PM_SLEEP
is set/enabled. OTOH, when both SUSPEND and HIBERNATION are not set,
PM_SLEEP is not set, so this variable cannot be used.

../drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c: In function ‘amdgpu_acpi_is_s0ix_active’:
../drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c:1046:11: error: ‘pm_suspend_target_state’ undeclared (first use in this function); did you mean ‘__KSYM_pm_suspend_target_state’?
    return pm_suspend_target_state == PM_SUSPEND_TO_IDLE;
           ^~~~~~~~~~~~~~~~~~~~~~~
           __KSYM_pm_suspend_target_state

Also use shorter IS_ENABLED(CONFIG_foo) notation for checking the
2 config symbols.
