spi: core: Only check bits_per_word validity when explicitly provided
On SPI device probe, the core will call spi_setup in spi_add_device
before the corresponding driver was probed. When this happens, the
bits_per_word member of the device is not yet set by the driver,
resulting in the default being set to 8 bits-per-word.
However some controllers do not support 8 bits-per-word at all, which
results in a failure when checking the bits-per-word validity.
In order to support these devices, skip the bits-per-word validity
check when it is not explicitly provided by drivers.
