mb/dell: Add Latitude E6530 (Ivy Bridge)

Browse source 
Mainboard is QALA0/LA-7761P (UMA). The version with a Nvidia dGPU was
not tested. I do not physically have this system; someone with physical
access to one sent me the output of autoport which I then modified to
produce this port.

I was also sent the vbios obtained using intel_bios_dumper while running
version A22 of the vendor firmware, which I then processed using
`intelvbttool --inoprom vbios.bin --outvbt data.vbt` to obtain data.vbt.

This was originally tested and found to be working as a standalone board
port in Libreboot, though this variant based port in upstream coreboot
has not been tested.

This can 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.
