OMAP3: PM: Set/clear T2 bit for Smartreflex on TWL
Voltage control on TWL can be done using VMODE/I2C1/I2C_SR.
Since almost all platforms use I2C_SR on omap3, omap3_twl_init by
default expects that OMAP's I2C_SR is plugged in to TWL's I2C
and calls omap3_twl_set_sr_bit. On platforms where I2C_SR is not connected,
the board files are expected to call omap3_twl_set_sr_bit(false) to
ensure that I2C_SR path is not set for voltage control and prevent
the default behavior of omap3_twl_init.
