The addition SPI quad support made the DT properties mandatory, breaking compatibility with existing systems. Fix that by making them optional, also improving the error messages while we're at it.

This certainly solves the following kernel error during boot:
spi_master spi32766: /spi@7000da00/spi-flash@1 has no 'spi-tx-nbits' property
But I'm still left with the following:
m25p80: probe of spi32766.1 failed with error -22
If instead of applying this patch, I revert the following:
db90a44 spi: conditional checking of mode and transfer bits. f477b7f spi: DUAL and QUAD support
Then everything works. I'll try and track down the remaining issue...
