95105089af clk: versal: Add clock driver support
This patch adds clock driver support for Versal platform. The clock driver
queries and performs clock operations using PLM firmware by communicating
with it using SMC calls.

3899ebdd88 arm64: zynqmp: Provide a Kconfig option to disable OCM and TCM MMU mapping
This patch provides an option to enable/disable OCM and TCM memory into MMU
table with corresponding memory attributes.

The same change was done for ZynqMP by commit 189bec47ab
("arm64: zynqmp: Provide a Kconfig option to define OCM and TCM in MMU")

aef149e9dd arm64: versal: Enable memory mapping via DT
Code reads DT and setup MMU table based on memory node. This will ensure
that only DT needs to be changed.

bfd092f9ca arm64: versal: Define board_late_init for versal
Define board_late_init which performs bootmode detection
and prepares corresponding distro boot commaand sequence.

Also disable it for mini platforms because simply there is no need to have
it enabled.
But also disable it for virtual platform because Qemu is not modelling this
register space that's why travis testing would fail. This configuration
should be reverted when mainline Qemu is updated.

ddccf5ef90 arm64: versal: Add Xilinx Versal Virtual QEMU board
Virtual QEMU board is generating DTB self and putting it to
VERSAL_QEMU_DTB_ADDR address.
Board is using CONFIG_OF_BOARD which ensures that u-boot is aligned with
board created by QEMU.

ec48b6c991 arm64: versal: Add support for new Xilinx Versal ACAPs
Xilinx is introducing Versal, an adaptive compute acceleration platform
(ACAP), built on 7nm FinFET process technology. Versal ACAPs combine
Scalar Processing Engines, Adaptable Hardware Engines, and Intelligent
Engines with leading-edge memory and interfacing technologies to deliver
powerful heterogeneous acceleration for any application. The Versal AI
Core series has five devices, offering 128 to 400 AI Engines. The series
includes dual-core Arm Cortex™-A72 application processors, dual-core Arm
Cortex-R5 real-time processors, 256KB of on-chip memory with ECC, more
than 1,900 DSP engines optimized for high-precision floating point with
low latency.

The patch is adding necessary infrastructure in place without enabling
platform which is done in separate patch.
