net: ipa: move ipa_aggr_granularity_val()
We only use ipa_aggr_granularity_val() inside "ipa_main.c", so it doesn't really need to be defined in a header file. It makes some sense to be grouped with the register definitions, but it is unlike the other inline functions now defined in "ipa_reg.h". So move it into "ipa_main.c" where it's used. TIMER_FREQUENCY is used only by that function, so move that definition as well. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
