The current GPIO definition for the MT7531 switch reset line incorrectly
specifies a pin GPIO_0 (GPIO5) that is connected to the boot mode
selection DIP switch (SW1).
In the public schematic for the BPI-R3 (titled "BPI-R3-MT7986A",
revision "V1.1", sheet 4), the SPI1_CS (GPIO32) pin of the MT7986 (U1E)
is connected to the GbE_RESET net.
Frank Wunderlich has told me, via the Banana Pi forum, that this GbE_RESET
net connects to the MT7531 reset line in the private part of the shematic
he has a copy of.
This commit needs a Fixes tag. After which,
