Fix the pci_epf_make() function so it can now bind many EPF devices to the
same EPF driver.

Add SPDX GPL-2.0 to all PCI files that specified the GPL version 2 license.
Remove the boilerplate GPL version 2 language, relying on the assertion in
b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to
files with no license") that the SPDX identifier may be used instead of the
full boilerplate text.

find_first_zero_bit()'s parameter 'size' is defined in bits,
not in bytes.
Calling find_first_zero_bit() with the wrong size unit
will lead to insidious bugs.
Fix this by calling find_first_zero_bit() with size BITS_PER_LONG,
rather than sizeof() and add missing find_first_zero_bit() return
handling.

func_no is a member of struct pci_epf.
Since struct pci_epf is used as an argument to pci_epc_add_epf() (to
bind an endpoint function to a controller), struct pci_epf.func_no
should be populated before calling pci_epc_add_epf().
Initialize the struct pci_epf.func_no member before calling
pci_epc_add_epf(), to fix the endpoint function binding to
an endpoint controller.

Make config_item_type structures const as they are either passed to a
function having the argument as const or stored in the const "ci_type"
field of a config_item structure.
Done using Coccinelle.

Introduce a new configfs entry to configure the EP function (like
configuring the standard configuration header entries) and to bind the EP
function with EP controller.
