ARM: dts: dra7: Change pbias voltage to 3.3V
As per recent TRM[1], PBIAS cell on dra7 devices supports 3.3v and not 3.0v as documented earlier. Update PBIAS regulator max voltage and the voltage written in the driver to reflect this. [1] http://www.ti.com/lit/pdf/sprui30 Signed-off-by: Faiz Abbas <faiz_abbas@ti.com>
