[U-Boot] [PATCH] power: pfuze100: Fix off by one error in voltage table handling

[Trent Piepho]

The code that sets a regulator by looking up the voltage in a table had
an off by one error.  vsel_mask is a bitmask, not the number of table
entries, so a vsel_mask value of 0x7 indicates there are 8, not 7,
entries in the table.
