Merge remote-tracking branches 'spi/fix/complete', 'spi/fix/efm32',...

Merge remote-tracking branches 'spi/fix/complete', 'spi/fix/efm32', 'spi/fix/omap2-mcspi' and 'spi/fix/qup' into spi-linus

- interrupts: pair specifying rx and tx irq
- clocks: phandle to the spi clock

Recommended properties :
- efm32,location: Value to write to the ROUTE register's LOCATION bitfield to
configure the pinmux for the device, see datasheet for values.
If "efm32,location" property is not provided, keeping what is
already configured in the hardware, so its either the reset
default 0 or whatever the bootloader did.
