The divider values in the sdcc1_apps frequency table were incorrectly
updated, assuming the frequency of gpll2_out_main to be 1152MHz.
However, the frequency of the gpll2_out_main clock is actually 576MHz
(gpll2/2).
Due to these incorrect divider values, the sdcc1_apps clock is running
at half of the expected frequency.
Fixing the frequency table of sdcc1_apps allows the sdcc1_apps clock to
run according to the frequency plan.

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.

Use the icc-clk framework to enable few clocks to be able to
create paths and use the peripherals connected on those NoCs.

The gcc_xo_clk is required for the functionality of the WiFi
copy engine block. Therefore, add the gcc_xo_clk in gcc driver.

The gcc_apss_dbg clk is access protected by trust zone, and accessing
it results in a kernel crash. Therefore remove the gcc_apss_dbg_clk
from the gcc driver.

The newly added driver causes a warnings when enabling -Wunused-const-variables:
drivers/clk/qcom/gcc-ipq5424.c:1064:30: error: 'ftbl_gcc_q6_axi_clk_src' defined but not used [-Werror=unused-const-variable=]
1064 | static const struct freq_tbl ftbl_gcc_q6_axi_clk_src[] = {

497 | static const struct freq_tbl ftbl_gcc_qupv3_2x_core_clk_src[] = {

In order to hopefully enable this warning by default in the future,
remove the data for now. If it gets used in the future, it can
trivially get added back.
