  [BOLT] Add support for Linux kernel PCI fixup section (#84982)

.pci_fixup section contains a table with entries allowing to invoke a
fixup hook whenever a problem is encountered with a PCI device. The
hookup code typically points to the start of a function. As we are not
relocating functions in the kernel (at least not yet), verify this
assumption while reading the table and ignore any functions with a fixup
code in the middle.
