This is a first step towards getting rid of avail_start and avail_end in the
kernel, currently limited to low-hanging fruit: these variables were used
by bus_dma to specify the range in which to allocate memory, back when
uvm_pglistalloc() was stupid and would not walk the vm_physseg[].
Nowadays, except on some platforms for early initialization, these variables
are not used, or do not need to be global variables. Therefore:
- remove `extern' declarations of avail_start and avail_end (or close cousins,
such as arm physical_start and physical_end) from files which no longer need
to use them.
- make them local variables whenever possible.
- remove them when they are assigned to but no longer used.
