ENGR00137958-2 Add mx53 smd&loco suspend via i2c command
Add mx53 smd&loco suspend via i2c command
Only a maximu 30ms delay before da9053 enter suspend, thus
the command is sent out at the latest stage of system suspend
operation when all other drivers already suspended and irq disabled.
A standalone polling-mode i2c interface is therefor deployed for the suspend
command operations.
In current solution, mx53 fails to resume from 1GHZ working poing when reduce
VDD &VCC to stop mode level. Thus a workaround is added to set mx53 working
point to 400MHZ before suspend and restore to previous working point after
it resume back.
