ARM: OMAP2+: pm: Use hwmod name instead of dev pointer

Browse Source 
Replace the struct device parameter of omap2_set_init_voltage
by the hwmod name. It will avoid having to store explicitely
the device pointer into a static variable.

Moreover, it will be a little bit more scalable if we introduce
new DVFS devices.
