Hi Heikki,

This series appliess some changes to the UCSI driver to help support AP
driven alternate mode entry. This includes...

1. An update to the altmode sysfs group after registration to make
"active" writable.
2. A change to the ucsi_partner_task delay when queuing
ucsi_check_altmodes to prevent it from running before other discovery
functions.
3. An update to always define a number of alternate modes for partners
and plugs.

Not related to AP driven altmode entry, there is an additional fix for a
null derefrence in this series.

I tested the series on a ChromeOS v6.8 kernel merged with usb-testing.
That build had some additinal patches to enable a PPM in ChromeOS. Let
me know if you have any questions.

Thanks,
Jameson
