Read up to 32 bytes. The ESCC *needs* 8, and it doesn't hurt to leave some
...
slop in case there are clone chips with a deeper FIFO.

Make zs_iflush not loop indefinitly. Some Mac PowerBooks lie about having
...
two SCC channels, and can get stuck in an infinite loop. This change
stops after flushing 4 bytes. Might need upping to 8 bytes if we support
85230 ESCC's.
Idea bounced off of scottr & gwr

Similar changes to com driver:
...
Arrange to call com_break() and com_modem() at splserial().
It's simpler this way. Really.

Remove the while loop from zsc_intr_hard(). It caused problems on
...
some machines, and those that really want to can just call this
function in a loop until it returns zero.

Rename cs_pclk_div16 to cs_brg_clk to clarify the fact that the

Baud Rate Generator (BRG) clock is not necessarily PCLK/16.

...
Make the pseudo-interrupt functions return void.
Call the tty layer at spltty (to be safe).
