[legacy] Allocate legacy driver .bss-like segments at probe time
Some legacy drivers use large static allocations for transmit and
receive buffers. To avoid bloating the .bss segment, we currently
implement these as a single common symbol named "_shared_bss" (which
is permissible since only one legacy driver may be active at any one
time).
Switch to dynamic allocation of these .bss-like segments, to avoid the
requirement for using common symbols.
