rtc: omap: restore back (hard-code) wakeup support

rtc-omap driver modules is used both by OMAP1/2, Davinci SoC platforms.

However, rtc wake support on OMAP1 is broken.  Hence the
device_init_wakeup() was removed from rtc-omap driver and moved to
platform board files that supported it (DA850/OMAP-L138).  [1]

However, recently [2] it was suggested that driver should always do a
device_init_wakeup(dev, true). Platforms that don't want/need
wakeup support can disable it from userspace via:

    echo disabled > /sys/devices/.../power/wakeup

Also, with the new DT boot-up, board file doesn't exist and hence there
is no way to have device wakeup support rtc.

The fix for above issues, is to hard code device_init_wakeup() inside
driver and let platforms that don't need this, handle it through the
sysfs power entry.
