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.
