Looking at this more closely it seems to me that it's a regulator thing
after all. In the end it all boils down to a single register write.
twl_i2c_write_u8(TWL_MODULE_PM_RECEIVER, 0x41, 0x8e);
This is a write to the CLK32KG_CFG_STATE [1] register to power on the
device.

I tried moving that to omap4xxx_dt_clk_init() but that won't work
because the twl core structures aren't initialized yet.

Any suggestions?
