Add symbols to mark end of TEXT/RODATA before page alignment.
Similar change was done by commit 8d69a03f6a ("Various
improvements/cleanups on the linker scripts") for
RO_END/COHERENT_RAM. These symbols help to know how much free
space is in the final binary because of page alignment.
Also show all *UNALIGNED__ symbols via poetry.
For example:
poetry run memory -p zynqmp -b debug

Fixes errors encountered when handling SVG graphics, unicode characters,
and deeply nested lists (i.e. in the change log) with the `latexpdf`
docs build. Adds `sphinxcontrib-svg2pdfconverter` to allow embedding SVG
images into PDF files; changes the LaTeX engine to XeLaTex to provide
wider support for unicode characters (see [1] for more details); and
increases the maximum list depth.

Add a new page in TF-A documentation for clarifying the process to
elect a new maintainer. This builds on top of the Trusted Firmware
process [1], with the following TF-A specific details:
- Must have contributed to the project for at least a couple of years.
- Must dedicate at least 2 hours a week for maintainer duties.
- Details about the election process. In particular, setting a
one-calendar-week deadline for other maintainers to raise
objections.

This patch adds a new optional member `pwr_domain_validate_suspend` to
the `plat_psci_ops_t` structure that allows a platform to optionally
perform platform specific validations in OS-initiated mode. This is
conditionally compiled into the build depending on the value of the
`PSCI_OS_INIT_MODE` build option.
In https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/17682,
the return type of the `pwr_domain_suspend` handler was updated from
`void` to `int` to allow a platform to optionally perform platform
specific validations in OS-initiated mode. However, when an error code
other than `PSCI_E_SUCCESS` is returned, the current exit path does not
undo the operations in `psci_suspend_to_pwrdown_start`, and as a result,
the system ends up in an unexpected state.
The fix in this patch prevents the need to undo the operations in
`psci_suspend_to_pwrdown_start`, by allowing the platform to first
perform any necessary platform specific validations before the PSCI
generic code proceeds to the point of no return where the CPU_SUSPEND
request is expected to complete successfully.
