fwmanager: Borrow the GPIO port in GpioBootMonitor

Owning the port swallowed a whole GPIO bank per monitor, making a
second monitor on the same bank impossible. On the AST1060 SGPIOM a
bank packs 32 unrelated lines, so distinct devices' ready signals
routinely share one bank by construction.

The monitor only reads (read_input takes &self), so hold &'a P instead:
several monitors can now watch different lines of the same bank, with
platform configuration keeping the bank alive for as long as its
monitors. Also note in the adapter docs that a single ready line only
ever yields the Booting/Booted subset of BootStatus.

Addresses review feedback on PR #368.
