OMAP3: Remove CONFIG_OMAP_SYSOFFMODE flag

Remove CONFIG_OMAP_SYSOFFMODE flag and do the full initialization of voltage
controller . Enabling automatic sending of OFF command and selecting wether
SYS_OFF_MODE signal is used should be determined dynamically. Hence they are
now not set in the initialization.

The sleep voltage for OFF mode is changed to default 1,2V for VDD1 and
1,15V for VDD2. Using the 0,9V setting causes hangup.
