[ Upstream commit 9bc4ffd32ef8943f5c5a42c9637cfd04771d021b ]
psci_init_system_suspend() invokes suspend_set_ops() very early during
bootup even before kernel command line for mem_sleep_default is setup.
This leads to kernel command line mem_sleep_default=s2idle not working
as mem_sleep_current gets changed to deep via suspend_set_ops() and never
changes back to s2idle.
Set mem_sleep_current along with mem_sleep_default during kernel command
line setup as default suspend mode.
Fixes: faf7ec4a92c0 ("drivers: firmware: psci: add system suspend support")
