feat(versal): add support to clear PM specific data

During a kexec restart, only the kernel is reloaded while TF-A state
remains unchanged, causing a mismatch between kernel and TF-A states.
To resolve this, add support for the TF_A_CLEAR_PM_STATE API, which
clears TF-A PM state.

fix(versal-net): add fallback on handoff failure

On the Versal-Net platform, booting can fail during ELF loading due to
the absence of a PLM handoff, preventing the system from booting
further.

To address this, a fallback mechanism has been introduced that allows
the boot process to continue even if the PLM handoff is not provided
only in debug builds with jtag boot mode.

fix(versal2): add ufs specific features support

Following IOCTL IDs are required for UFS specific functionalities.

IOCTL ID - 40(IOCTL_UFS_TXRX_CFGRDY_GET)
This gives the Tx_Rx_config_rdy_signal_mon(0xF1061054) register value
which contains the Tx and Rx lanes configuration ready signal information.

IOCTL ID - 41(IOCTL_UFS_SRAM_CSR_SEL)
Select - 0(IOCTL_UFS_SRAM_CSR_SET)
This will allow to set sram control and status register (0xF106104C)
with the value provided by driver.

Select - 1(IOCTL_UFS_SRAM_CSR_GET)
This should return the sram control and status register (0xF106104C) value
to the driver.

UFS Host reset assert/de-assert(using SCMI) support is added.
register address : 0xF1260340

UFS PHY reset assert/de-assert(using SCMI) support is added.

Today, the PM_IOCTL and PM_QUERY_DATA APIs are there to maintain
backward compatibility. Now, the usage of these APIs on the Linux
side and the firmware side is updated. Hence remove the deprecated
PM_IOCTL and PM_QUERY_DATA EEMI API from the TF-A to make TF-A pass
through.

Note: Only use the newer kernel to access the deprecated features in
this patch. Otherwise, the system may not function correctly.

feat(xilinx): add new state to identify cpu power down

Currently there is only 1 state for CPU idle which is used while CPU
power down from Linux CPU idle feature. But CPU power down when firmware
send CPU power down request needs new state in self suspend to
distinguish in firmware for CPU power down from power down request or CPU
power down from Linux CPU idle. So add new state PM_STATE_CPU_OFF to
indicate CPU power down from power down request from firmware.

PM_STATE_CPU_OFF state is supported from self-suspend version 3. So
added feature check which sends new state in case of new firmware and
old state i.e. PM_STATE_CPU_IDLE in case of old firmware.

As per the current code base, PM_CLOCK_SETRATE and PM_CLOCK_GETRATE
APIs are not supported for the runtime operations in the firmware and
the TF-A it is already returning an error when there is any request
to access these APIs. So, just removing the unused code to avoid the
confusion around these APIs.

Also, there is no issue with the backward compatibility as these APIs
were never used since implemented. Hence no need to bump up the
version of the feature check API as well.
