ANDROID: GKI: add allowed list for Exynosauto SoC

This patch adds GKI symbol list for Exynosauto SoC. We need to add
below 8 function symbols and it required by PCIe RC/EP driver.

8 function symbol(s) added
  'int pci_epc_map_addr(struct pci_epc*, u8, u8, phys_addr_t, u64, size_t)'
  'void* pci_epc_mem_alloc_addr(struct pci_epc*, phys_addr_t*, size_t)'
  'void pci_epc_mem_free_addr(struct pci_epc*, phys_addr_t, void*, size_t)'
  'int pci_epc_set_bar(struct pci_epc*, u8, u8, struct pci_epf_bar*)'
  'void pci_epc_unmap_addr(struct pci_epc*, u8, u8, phys_addr_t)'
  'void* pci_ioremap_wc_bar(struct pci_dev*, int)'
  'int pci_num_vf(struct pci_dev*)'
  'int pci_request_regions(struct pci_dev*, const char*)'
