Doc/mb/lenovo/Sandy_Bridge_series.md: Clarify installation
Unlike Ivy Bridge series, there isn't a method to flash coreboot internally when running vendor firmware (yet). Until someone finds a way to bypass flash protections, the first flash has to be done externally.

## Installation instructions
+
+Flashing coreboot for the first time needs to be done using an external
+programmer, because vendor firmware prevents rewriting the BIOS region.
+
* Update the EC firmware, as there's no support for EC updates in coreboot.
* Do **NOT** accidentally swap pins or power on the board while a SPI flasher
is connected. It will destroy your device.
