Pin control fixes for the v5.17 series:

Browse Source 
- Fix some drive strength and pull-up code in the K210 driver.
 
 - Add the Alder Lake-M ACPI ID so it starts to work properly.
 
 - Use a static name for the StarFive GPIO irq_chip, forestalling
   an upcoming fixes series from Marc Zyngier.
 
 - Fix an ages old bug in the Tegra 186 driver where we were
   indexing at random into struct and being lucky getting the
   right member.
