This mirrors the update process over DP aux to run the ESM update
first.
The thought process is as follows:
The "version" displayed doesn't show ESM version, only standard
bank version.
So if the update fails for the ESM then because the update of the
standard happening first it would never be flashed.
Since dell_dock is the priority plugin for MST flashing the VMM5331
no need to do delayed callbacks anymore.
When the dell_dock plugin bumps to EC 15 being the minimum requirement
more code can also be dropped.
It was identified that at least one other device on this shared
I2C bus can't operate at the speed. This means that it may
inadvertently respond to commands intended for another device.
The libxmlb library is much faster to query, and does not require the daemon
to parse the XML metadata at startup. It's a zero-copy mmap design that is more
modern and less clunky.
RSS has reduced from 3Mb (peak 3.61Mb) to 1Mb (peak 1.07Mb) and the startup
time has gone from 280ms to 250ms.
This plugin requires infrastructure introduced in fwupd 1.1.3
and can not be backported to earlier versions of fwupd.
It works together with the Synaptics and Thunderbolt plugins to
coordinate the proper flashing procedure for devices in this dock.
