commit 579af7204d762587f9cce0d6236a710a771f1f6f upstream.

The following errors were reported for a s390 randconfig build
of the fluke gpib driver:

>> drivers/gpib/eastwood/fluke_gpib.c:1002:23: error: call to undeclared function 'ioremap'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
1002 | nec_priv->mmiobase = ioremap(e_priv->gpib_iomem_res->start,
| ^
>> drivers/gpib/eastwood/fluke_gpib.c:1002:21: error: incompatible integer to pointer conversion assigning to 'void *' from 'int' [-Wint-conversion]
1002 | nec_priv->mmiobase = ioremap(e_priv->gpib_iomem_res->start,
| ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1003 | resource_size(e_priv->gpib_iomem_res));
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpib/eastwood/fluke_gpib.c:1036:33: error: incompatible integer to pointer conversion assigning to 'void *' from 'int' [-Wint-conversion]
1036 | e_priv->write_transfer_counter = ioremap(e_priv->write_transfer_counter_res->start,
| ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1037 | resource_size(e_priv->write_transfer_counter_res));
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Add HAS_IOMEM dependency to Kconfig for fluke driver option
