board: ti: am43xx: take care of all OPPs
Make sure that all OPPs are checked on scale_vcores(). While at that also fix 600MHz VDD_MPU voltage according to AM437x Data Manual available at [1]. Table 5-3 on that document, lists all valid voltages per frequency. [1] http://www.ti.com/lit/ds/symlink/am4379.pdf Signed-off-by: Felipe Balbi <balbi@ti.com>
