This iteration introduces a key improvement: the ti_sci driver now restores
SCI clock parents during resume as the firmware is not able to do it.
On the interrupt management side, the driver has been updated to use hlist
for storing requested IRQs.
Regarding documentation, Nishanth requested references for
BOARDCFG_MANAGED mode. While the relevant documentation is not yet publicly
available, I will update the commit message with the appropriate links as
soon as it becomes accessible.
