From: Ajay Singh <ajay.kathat@xxxxxxxxxxxxx>
For power-up sequence, WILC expects RESET set to high 5ms after making
chip_en(enable) so corrected chip power-up sequence by making RESET high.
For Power-Down sequence, the correct sequence make RESET and CHIP_EN low
without any extra delay.
Fixes: ec031ac4792c ("wilc1000: Add reset/enable GPIO support to SPI driver")
