Paolo Bonzini ac2c4d3aed rust: pl011: Really use RX FIFO depth
While we model a 16-elements RX FIFO since the PL011 model was
introduced in commit cdbdb648b7 ("ARM Versatile Platform Baseboard
emulation"), we only read 1 char at a time!

Have can_receive() return how many elements are available, and use that
in receive().

This is the Rust version of commit 3e0f118f82 ("hw/char/pl011: Really
use RX FIFO depth"); but it also adds back a comment that is present
in commit f576e0733c ("hw/char/pl011: Add support for loopback") and
absent in the Rust code.
