Merge tag 'i2c-host-6.10-pt2' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current

Removed the SPD class of i2c devices from the device core.

Additionally, a cleanup in the Synquacer code removes the pclk
from the global structure, as it is used only in the probe.
Therefore, it is now declared locally.
