mb/up/squared: Make mini PCIe port mode configurable

Add ENABLE_MSATA config knob and pad configuration to put Mini PCIe port
into mSATA mode.

The vendor firmware's "Chipset->Mini PCIe / mSATA Switch" option has
been used together with the output of inteltool and intel2pm to deduce
the exact pad configuration.

Note: the vendor firmware does not autodetect the mode, and the default
setting for the port is "Mini PCIe".

Tested with Kingston SUV500MS120G mSATA SSD.
