[2/10] remove ISA legacy functions: drivers/net/arcnet/

[Adrian Bunk]

From: Al Viro <viro@zeniv.linux.org.uk>

sanitized probing code, made sure we claim regions before poking into
them (original tried that to some extent, but hadn't got it right),
switched to ioremap() use in probing.

The order of the hunks in the patch was slightly rearranged due to an 
unrelated change in the driver.

hp100 has ->mem_ptr_virt set for all memory-mapped cases; removed
rudiment of old version that used ioremap() only when physical
address wasn't an ISA one.  These days it's simply a dead code.
