clk: qcom: clk-rcg2: Make sure to not write d=0 to the NMD register

Browse source

[ Upstream commit d0696770ce ]

Sometimes calculation of d value may result in 0 because of the
rounding after integer division. This causes the following error:

[  113.969689] camss_gp1_clk_src: rcg didn't update its configuration.
[  113.969754] WARNING: CPU: 3 PID: 35 at drivers/clk/qcom/clk-rcg2.c:122 update_config+0xc8/0xdc

Make sure that D value is never zero.
