staging: wilc1000: updated DT binding documentation
Merged the DT binding documentation of SDIO and SPI into a single file. Removed documentation for some of the properties which are not required and handled review comments received in [1] & [2]. [1]. https://lore.kernel.org/linux-wireless/20200303020230.GA15543@bogus [2]. https://lore.kernel.org/linux-wireless/20200303015558.GA6876@bogus Signed-off-by: Ajay Singh <ajay.kathat@microchip.com> Link: https://lore.kernel.org/r/20200307085523.7320-4-ajay.kathat@microchip.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
