ARM: OMAP4: Fix bug in omap4470_volts struct
The struct incorrectly referenced SMPS1 for all three power domains. Fixed this by using SMPS2 and SMPS5 as appropriate. Add some comments and choose voltage values that correspond to voltage selection codes. Signed-off-by: Lubomir Popov <l-popov@ti.com>
