    rtw88: Add bus attachments to the module Makefile
    
    In addition to PCIe we will support USB and also prepare for SDIO (still
    disabled locally).  The module SRCS are split up into a common part,
    which we always add.  All three bus parts are guarded by a local
    variable in the Makefile.
    In addition the PCI parts require PCI to be compiled into the kernel.
    We add that check in case of, e.g., SoCs with SDIO but no PCI, which
    may not have PCI in the kernel config and thus the module would fail
    to attach.
    USB has no additional check as it is fully loadable and does not have
    to be in a kernel config.
    SDIO depends on an MMCCAM-enabled kernel but is otherwise loadable.
    
    While we could, we are not splitting the various bus attachments into
    individual modules as we generally do not do that in FreeBSD. [1]
