Subject: [PATCH 26/30] mb/dell: Add Latitude E6530 (Ivy Bridge)

Mainboard is QALA0/LA-7761P (UMA). The dGPU model was not tested.  This
is based on the autoport output with some manual tweaks. The flash is
8MiB + 4MiB. It 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.
