ARM: OMAP2+: pm: Use hwmod name instead of dev pointer
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. Signed-off-by: Benoit Cousson <b-cousson@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
