misc: pci_endpoint_test: Remove unused pci_endpoint_test_bar_{readl,writel} functions

These two functions are defined in the pci_endpoint_test.c file, but not
called elsewhere, so delete these unused functions.

This fixes the following warning:

  drivers/misc/pci_endpoint_test.c:144:19: warning: unused function 'pci_endpoint_test_bar_readl'.
  drivers/misc/pci_endpoint_test.c:150:20: warning: unused function 'pci_endpoint_test_bar_writel'.

No functional changes intended.
