apalis_t30: ixora: optionally support leds, switch, foff and wdisable
The Ixora carrier board has a few MXM3 pins repurposed as follows:
Functionality MXM3 Pin
LED4_RED 146
LED4_GREEN 162
LED5_RED 156
LED5_GREEN 152
PCIE1_WDISABLE_N 144
SW3 160
UART2_3_RS232_FOFF_N 164
This patch allows uncommenting an IXORA define in the board header file
in order to make use of those repurposed pins.
Please note that those pins are usually used for the 8-bit MMC/SD slot
aka Apalis MMC1 and the SDHCI controller/driver unfortunately changes
the output driver behaviour in a way preventing any regular GPIO use.
This patch therefore explicitly does not register the SDHCI driver on
this controller instance in the Ixora case to avoid this.
