Nico Huber e6b0a32cb3 libpayload: Make 8250 UART driver relocation safe
`lib_sysinfo->serial` is a virtual pointer into coreboot tables.
It's not valid across relocation. Accessing the wrong value during
relocation of FILO resulted in a hang with DEBUG_SEGMENT and UART
console enabled. Work around that by caching the whole table entry
locally.

An alternative would be to revise `sysinfo`, to contain no virtual
pointers to anything outside the payload.
