clk: qcom: gcc-ipq8074: fix broken freq table for nss_port6_tx_clk_src

commit 077ec7bcec9a8987d2a133afb7e13011878c7576 upstream.

With the conversion done by commit e88f03230dc0 ("clk: qcom: gcc-ipq8074:
rework nss_port5/6 clock to multiple conf") a Copy-Paste error was made
for the nss_port6_tx_clk_src frequency table.

This was caused by the wrong setting of the parent in
ftbl_nss_port6_tx_clk_src that was wrongly set to P_UNIPHY1_RX instead
of P_UNIPHY2_TX.

This cause the UNIPHY2 port to malfunction when it needs to be scaled to
higher clock. The malfunction was observed with the example scenario
with an Aquantia 10G PHY connected and a speed higher than 1G (example
2.5G)

Fix the broken frequency table to restore original functionality.
