Michael Brown 4d6c8ab443 [usb] Add USB_ROM() and USB_ID() macros
Add USB_ROM() and USB_ID() macros following the pattern for PCI_ROM()
and PCI_ID(), to allow for the possibility of including USB network
devices within the "all-drivers" build of iPXE.

Michael Brown adcaaf9b93 [build] Mark known reviewed files as permitted for UEFI Secure Boot
Some past security reviews carried out for UEFI Secure Boot signing
submissions have covered specific drivers or functional areas of iPXE.
Mark all of the files comprising these areas as permitted for UEFI
Secure Boot.

Michael Brown 6d680bdec5 [usbblk] Add support for USB mass storage devices
Some UEFI BIOSes (observed with at least the Insyde UEFI BIOS on a
Microsoft Surface Go) provide a very broken version of the
UsbMassStorageDxe driver that is incapable of binding to the standard
EFI_USB_IO_PROTOCOL instances and instead relies on an undocumented
proprietary protocol (with GUID c965c76a-d71e-4e66-ab06-c6230d528425)
installed by the platform's custom version of UsbCoreDxe.

The upshot is that USB mass storage devices become inaccessible once
iPXE's native USB host controller drivers are loaded.

One possible workaround is to load a known working version of
UsbMassStorageDxe (e.g. from the EDK2 tree): this driver will
correctly bind to the standard EFI_USB_IO_PROTOCOL instances exposed
by iPXE.  This workaround is ugly in practice, since it involves
embedding UsbMassStorageDxe.efi into the iPXE binary and including an
embedded script to perform the required "chain UsbMassStorageDxe.efi".

Provide a native USB mass storage driver for iPXE, allowing USB mass
storage devices to be exposed as iPXE SAN devices.
