wifi: wilc1000: use correct sequence of RESET for chip Power-UP/Down
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.
