[PATCH] platform/x86/intel/tpmi: Change vsec offset to u64

[Srinivas Pandruvada]

The vsec offset can be 64 bit long depending on the PFS start. So change
type to u64. Also use 64 bit formatting for seq_printf.

This is a forward looking change. There is no platform with this issue.
This can go through regular cycle.

I've applied this to review-ilpo.
