Some of the divider settings are preconfigured and should not
be changed by the clock framework during frequency change. This
patch adds the read-only divider operation for QCOM dividers
which is equivalent to generic divider operations in
'commit 79c6ab50 ("clk: divider: add CLK_DIVIDER_READ_ONLY flag")'.
