Since readl() returns a u32, the local variables reg and bypass can also
have the data type u32. Furthermore, divf and divq are derived from reg
and can also be a u32.
Since do_div() casts the divisor to u32 anyway, changing the data type
of divq to u32 removes the following Coccinelle/coccicheck warning
reported by do_div.cocci:
WARNING: do_div() does a 64-by-32 division, please consider using div64_ul instead
Compile-tested only.
