Add Dell Latitude E6430

This was only tested on the iGPU model, though a dGPU model does exist.
The vendor firmware used a 16KiB gbe.bin, which was modified with a
random MAC address as well as shrinking it to 8KiB. As with the E6400,
GRUB doesn't like the way the EC implements the keyboard controller and
thus GRUB payloads are disabled at this time. Suspend does not currently
work, and this is believed to be due to the EC controlling the DRAM
reset gate which is required to prevent DRAM from being reset on resume.

With some tweaks, the e6400-flash-unlock utility also works on this
system, though both flash chips can be accessed through removal of only
the keyboard.

+Subject: [PATCH 1/3] ec/dell/mec5035: Add command to enable/disable radios
+
+These were determined by sniffing the LPC bus while toggling the
+hardware wireless switch on the Latitude E6400. To differentiate devices
+options in the vendor BIOS to change which radios the switch controlled
+were used.

+Subject: [PATCH 3/3] mb/dell: Add Latitude E6430 (Ivy Bridge)
+
+Mainboard is QAL80/LA-7781P (UMA). The dGPU model was not tested.
+This is based on the autoport output with some manual tweaks. The flash
+is 8MiB + 4MiB, and is fairly easily accessed by removing the keyboard.
+It can also be internally flashed by sending a command to the EC, which
+causes the EC to pull the FDO pin low and the firmware to skip setting
+up any chipset based write protections. [1] The EC is the SMSC MEC5055,
+which seems to be compatible with the existing MEC5035 code.
+
+Working:
+- Libgfxinit
+- USB EHCI debug (left side usb port is HCD index 2, middle port on the
+  right side is HCD index 1)
+- Keyboard
+- Touchpad/trackpoint
+- ExpressCard
+- Audio
+- Ethernet
+- SD card reader
+- mPCIe WiFi
+- SeaBIOS 1.16.2
+- edk2 (MrChromebox' fork, uefipayload_202306)
+- Internal flashing
+
+Not working:
+- S3 suspend: It seems like the EC also controls the DRAM reset gate so
+  there may be a command that needs to be implemented for this
+- Physical Wireless switch
+- Battery reporting
+- Brightness hotkeys
+
+Unknown/untested:
+- Dock
+- eSATA
+- TPM
+- dGPU on non-UMA model
