PCI: pci-bridge-emul: Fix array overruns, improve safety
We allow up to PCI_EXP_SLTSTA2 registers to be accessed, but the
pcie_cap_regs_behavior[] array only covers up to PCI_EXP_RTSTA. Expand
this array to avoid walking off the end of it.
Do the same for pci_regs_behavior for consistency[], and add a
BUILD_BUG_ON() to also check the bridge->conf structure size.
Fixes: 23a5fba4d941 ("PCI: Introduce PCI bridge emulated config space common logic")
