wifi: brcmfmac: support CYW54591 PCIE device
CYW54591 is a variant of BCM4355 silicon with the same chipid. In the
chipid-fwname mapping table, apply chiprev 13 to identify CYW54591.
Skip reading OTP process for CYW chip since it contains vendor specific
information which is not common for cypress.
