clk: qcom: ipq5424: fix software and hardware flow control error of UART

The UART’s software and hardware flow control are currently not
functioning correctly.

For software flow control, the following error is encountered:
qcom_geni_serial 1a80000.serial: Couldn't find suitable
clock rate for 56000000, 3500000, 2500000, 1152000, 921600, 19200

During hardware flow control testing, a “Retry 0: Got ZCAN error” is
observed.

To address these issues, update the UART frequency table to include all
supported frequencies according to the frequency plan.
