PCI: cadence: Configure LM_EP_FUNC_CFG based on epc->function_num_map
The number of functions supported by the endpoint controller is configured
in LM_EP_FUNC_CFG based on func_no member of struct pci_epf. Now that an
endpoint function can be associated with two endpoint controllers (primary
and secondary), just using func_no will not suffice as that will take into
account only if the endpoint controller is associated with the primary
interface of endpoint function. Instead use epc->function_num_map which
will already have the configured functions information (irrespective of
whether the endpoint controller is associated with primary or secondary
interface).
