The attribute call-backs all use the same formula to get the pcard from
dev:

  struct pci_dev *pdev = to_pci_dev(dev);
  struct kp2000_device *pcard;

  if (!pdev)
    return -ENXIO;
  pcard = pci_get_drvdata(pdev);
  if (!pcard)
    return -ENXIO;

Added a function to reduce the duplicated code.

The arcx-anybus's registers are accessed via a memory-mapped
IO region. A regmap associated with this region is created
using custom reg_read() / reg_write() callbacks.

However, an abstraction which creates a memory-mapped IO
region backed regmap already exists: devm_regmap_init_mmio().

Replace the custom regmap with the existing kernel abstraction.

staging: kpc2000: added separate show functions for kpc_uio_class device attributes, defined them as read-only and declared them static.

Defined separate simple show functions for each attribute instead of
having a one big one containing a chain of conditionals.

Replaced scnprintf calls with sprintf since all the outputs are short
bounded strings or single integers.

All of the device attributes are read-only, so used DEVICE_ATTR_RO to
define them.

The definitions are only used to populate the kpc_uio_class_attrs
attribute array, so declared them as static.

Fixes the following sparse warnings:
