fsl_pci_ep: fix checking PCI register size
For T4240, the first PCI controller whose register size is 0x10000,
has two physical functions and each physical function register size
is 0x2000. But for some older platform PCI controller size is 0x1000
less than 0x2000. The original checking of PCI register size is
mistaken. The patch is to fix this issue.
