clk: qcom: gcc-ipq6018: rework nss_port5 clock to multiple conf

Browse Source 
Rework nss_port5 to use the new multiple configuration implementation
and correctly fix the clocks for this port under some corner case.

In OpenWrt, this patch avoids intermittent dmesg errors of the form
nss_port5_rx_clk_src: rcg didn't update its configuration.

This is a mechanical, straightforward port of
commit e88f03230d
("clk: qcom: gcc-ipq8074: rework nss_port5/6 clock to multiple conf")
to gcc-ipq6018, with two conflicts resolved: different frequency of the
P_XO clock source, and only 5 Ethernet ports.

This was originally developed by JiaY-shi <shi05275@163.com>.
