clk: sunxi: Fix operator precedence in sunxi_divs_clk_setup
r375326 in Clang exposes an issue with operator precedence in
sunxi_div_clk_setup:
drivers/clk/sunxi/clk-sunxi.c:1083:30: warning: operator '?:' has lower
precedence than '|'; '|' will be evaluated first
[-Wbitwise-conditional-parentheses]
data->div[i].critical ?
~~~~~~~~~~~~~~~~~~~~~ ^
drivers/clk/sunxi/clk-sunxi.c:1083:30: note: place parentheses around
the '|' expression to silence this warning
data->div[i].critical ?
^
)
drivers/clk/sunxi/clk-sunxi.c:1083:30: note: place parentheses around
the '?:' expression to evaluate it first
data->div[i].critical ?
^

1 warning generated.
It appears that the intention was for ?: to be evaluated first so that
CLK_IS_CRITICAL could be added to clkflags if the critical boolean was
set; right now, | is being evaluated first. Add parentheses around the
?: block to have it be evaluated first.
