fix(xilinx): match function type as its declared

This corrects the MISRA violation C2012-8.3:
matching the type of function definition as per its declaration.

refactor(xilinx): move plat_get_syscnt_freq2 to common file

The code in the AMD-Xilinx platform for Versal and Versal NET is being
refactored to move the plat_get_syscnt_freq2() function to a common
file. This common function is utilized for obtaining the CPU clock
frequency from the platform.

fix(versal): initialize cntfrq_el0 register

The set_cnt_freq() function is introduced to configure the counter
frequency register.If the counter frequency register is zero, it writes
the output of plat_get_syscnt_freq2() the cpu_clocks to the counter
frequency register.

According to the design specifications provided for Versal, the
lpd_data.cdo file contains a mask_write operation for register
0xFF140020 (base_frequency_ID_register) to set it to 0x5f5e100,
configuring it for a 100MHz clock frequency.

Reading the value of the IOU_SCNTRS_BASE_FREQ register using
mmio_read_32() to determine the counter frequency. If the counter
frequency is zero, the system will set the default CPU clocks constants
in TF-A and displays message. However, if the counter frequency is
non-zero, the program will return the value stored in the
IOU_SCNTRS_BASE_FREQ register.

The issue lies in dcc_status_timeout(),function verifying timeout
status, particularly within timeout_cnt_us2cnt(), converting
microseconds to counter ticks using read_cntfrq_el0(), which returns
zero. timeout_elapsed() then checks if the current counter from
read_cntpct_el0()exceeds the expiration count, denoting timeout.

After the function set_cnt_freq() writes into the counter frequency
register, the function timeout_cnt_us2cnt() is used to obtain the
appropriate counter ticks. Subsequently, the function timeout_elapsed()
checks whether the current counter value read_cntpct_el0() has
exceeded the specified expiration count. If it has, this indicates
that the timeout has lapsed.
