Several drivers can benefit from registering per-instance data along
with the syscore operations. To achieve this, move the modifiable fields
out of the syscore_ops structure and into a separate struct syscore that
can be registered with the framework. Add a void * driver data field for
drivers to store contextual data that will be passed to the syscore ops.

This change is fine with me, so I can apply it unless somebody has any
specific heartburn related to it (Greg?), but in case you want to
route it differently

I have a few follow-up patches for the Tegra PMC driver that depend on
this. 6.19 is what I was targetting, so if we could put this into a
stable branch that'd be the best solution. I can set that up via the
Tegra tree if you and Greg are okay with it.

If that's all too complicated, I can probably wait until the next cycle
to merge the PMC changes.
I've added this single patch to a branch based off of v6.18-rc1 that I
plan to feed into linux-next so it can get some broader exposure.

I can keep that branch stable so it can go through multiple trees if
needed. If anyone's interested, the branch is here:
