[ Upstream commit 0c32840763b1579c923b4216c18bb756ca4ba473 ]
Usage of the telem sysfs file allows for partial reads at an offset.
The current callback method returns the buffer starting from offset 0
only.
Include the requested offset in the callback and update the necessary
address calculations with the offset.
Note: offset addition is moved from the caller to the local usage. For
non-callback usage this is unchanged behavior.

Some PMT providers require device specific actions before their telemetry
can be read. Provide assignable PMT read callbacks to allow providers to
perform those actions.

Some drivers outside of PDX86 need access to the vsec header. Move it to
include/linux to make it easier to include.
