[PATCH] clk: samsung: gs101: Fix missing USI7_USI DIV clock in peric0_clk_regs

[Kuan-Wei Chiu]

In the peric0_clk_regs array, the divider register offset for USI6 was
accidentally listed twice, while the divider for USI7 was omitted.

Missing this DIV register causes the USI7 clock divider setting to be
lost and reset to its hardware default value during a suspend/resume
cycle.

Replace the duplicated USI6 DIV entry with the correct USI7 DIV
register.

Build test only. Found via manual review.
Setting up an upstream kernel on hardware would probably take
considerable effort right now. Since this is an obvious typo, I'm
submitting it compile tested only.
