cxl: Free virtual PHB when removing



When adding a vPHB in cxl_pci_vphb_add(), we allocate a pci_controller
struct using pcibios_alloc_controller(). However, we don't free it in
cxl_pci_vphb_remove(), causing a leak.

Call pcibios_free_controller() in cxl_pci_vphb_remove() to free the vPHB
data structure correctly.
