[PATCH 1/3] e1000e: e1000e_cyclecounter_read(): incvalue is 32 bits, not 64

[Denys Vlasenko <dvlasenk@redhat.com>]

"incvalue" variable holds a result of "er32(TIMINCA) & E1000_TIMINCA_INCVALUE_MASK"
and used in "do_div(temp, incvalue)" as a divisor.

Thus, "u64 incvalue" declaration is probably a mistake.
Even though it seems to be a harmless one, let's fix it.
