Add zipl and zipl.conf man page updates.
The zipl man page will look like:
-S <SWITCH> or --secure <SWITCH>
Control the zIPL secure boot support. <SWITCH> can take one of three values:
auto (default)
Write signatures if available and supported by the system.
1
Signatures are written independent of support indicated by the local
system. Also missing signatures for stage 3 and kernel IPL files
will result in an error.
0
No signatures will be written.
The zipl.conf man page will look like:
secure = auto/1/0 (configuration only)
Configuration section:
Control the zIPL secure boot support. Set this option to one of the following:
- auto: Write signatures if available and supported by the system.
- 1: Signatures are written independent of support indicated by the local system.
Also missing signatures for stage 3 and kernel IPL files will result in an error.
- 0: No signatures will be written.
The default value for 'secure' is auto.

The BootLoaderSpec (BLS) defines a file format for boot configurations,
so bootloaders can parse these files and create their boot menu entries
by using the information provided by them [0].
This allow to configure the boot items as drop-in files in a directory
instead of having to parse and modify a bootloader configuration file.
If the /boot/loader/entries exists and there are BLS files there, then
these are parsed and configuration sections are added without the need
to have these in a zipl.conf file.
A different BLS directory can be specified from the command line using
the --blsdir option.
