soc/amd/stoneyridge: Fix smi_write32 arg order in disable_all_smi_status
The argument order for smi_write32() is offset, value. Current code had it backwards. So, when disable_all_smi_status() was called by sb_slp_typ_handler(), instead of clearing pending flag SlpTypeEvent65 (0x2) in SMIx88 SmiStatus2 by writing 0x00000002 to 0xfed80288, it would instead write 0x00000088 to 0xfed80202 - clearing the lower 2 bytes of SMIx04 Event_Enable, which disabled the lower 16 GPEs from waking the system from S3. Thus, the EC events (Keyboard / lid switch) [GPE15] and touchpad [GPE7] did not work as wake up sources. BUG=b:78461678 TEST=powerd_dbus_suspend, tapping any key on keyboard wakes from S3.
