mxser: drop ISA support

While mxser PCI cards are still around and produced (Moxa provided me
with two recently), ISA cards are obsolete for a long time. I haven't
seen anyone using the cards and the ISA code paths are barely tested.

Hence, remove ISA support from mxser driver so that we can clean the
driver up.

-    For PCI boards user, please skip this step.

-    In module mode, the CAP address for ISA board is given by

-    The instructions to modify driver source code are as

-
-    a. run::
-
-	# cd /moxa/mxser/driver
-	# vi mxser.c
-
-    b. Find the array mxserBoardCAP[] as below::
-
-	  static int mxserBoardCAP[] = {0x00, 0x00, 0x00, 0x00};

-       0x280 and 0x180 as 1st and 2nd board. Just to change
