Add missing documentation for the parameters "ntb_epc", "type", "dev",
and "group" of the following functions:
- epf_ntb_add_cfs()
- epf_ntb_alloc_peer_mem()
- epf_ntb_config_sspad_bar_clear(),
- epf_ntb_config_sspad_bar_set()
- epf_ntb_peer_spad_bar_clear()
- epf_ntb_peer_spad_bar_set()
- pci_epc_remove_epf()
Remove surplus parameter from the epf_ntb_init_epc_bar() function.
Additionally, fix a non-compliant kernel-doc at the top of the files
pci-epf-ntb.c and pci-epf-test.c, and resolve number of build time
warnings related to kernel-doc:

Fix kernel-doc formatting and add missing documentation for the "node"
parameter of the of_get_pci_domain_nr() and of_pci_get_max_link_speed()
functions, and resolve build time warnings related to kernel-doc:
drivers/pci/of.c:202: warning: expecting prototype for This function
will try to obtain the host bridge domain number by(). Prototype was
for of_get_pci_domain_nr() instead
drivers/pci/of.c:597: warning: expecting prototype for This function
will try to find the limitation of link speed by finding(). Prototype
was for of_pci_get_max_link_speed() instead
No change to functionality intended.

Applied all to pci/kernel-doc, thanks! I squashed them into one patch
since these only change comments.
