docs/mb/supermicro/x11ssm-f: rework flashing section
The board can be flashed without adding a diode by just leaving VCC unconnected. Rework the flashing section to describes that.

## Flashing coreboot
-The board can be flashed externally. FTDI FT2232H and FT232H based programmers worked. For this, -one needs to add a diode between VCC and the flash chip. The flash IC [MX25L12873F] can be found -near PCH PCIe Slot 4. +The flash IC [MX25L12873F] can be found near PCH PCIe Slot 4. + +The board can be flashed externally with a SOIC test clip or probes. Since +there is no diode between VCC3.3 and the flash chip, so VCC must **not** be +connected. Instead, the flash chip is powered from VCC3.3, which is always-on +(even in S5).

Flashing is also possible through the BMC web interface, when a valid license was entered.
