feat(versal): add support for TFA_NO_PM configuration

For Versal APU validation in Zephyr CI it is useful to run only one QEMU
instance and not model PLM (Platform Loader and Manager). That's why
implement TFA_NO_PM compilation flag to cover it. That's why don't call
any PM initialization or communication via IPI with PLM. Flag is
aligned with implementations done in Versal NET or Versal Gen 2.

QEMU COSIM introduces a new platform id for Versal Platform.

fix(versal): kernel QEMU boot is failing on versal platform

Due to deprecation of VERSAL_PLATFORM build argument,
the board detection is done at runtime due to this the cpu
and uart clock freq was not set as required to silicon values.

Updated Versal QEMU cpu_clock and uart_clock to silicon values.

feat(versal): deprecate build time arg VERSAL_PLATFORM

Update Versal platform to enable runtime detection of variants instead
of relying on the build argument VERSAL_PLATFORM.
Integrate functionality for identifying the board variant during
runtime, allowing dynamic adjustment of CPU and UART clock values
accordingly.
Print the runtime board information during boot.
This advancement streamlines the build process by eliminating
dependencies on variant-specific builds, enabling the use of a single
binary for multiple variants.
Removing all the platform related constants for versal_virt,SPP,EMU as
they are not used.

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.
