[PATCH 5.19 0324/1157] wifi: wilc1000: use correct sequence of RESET for chip Power-UP/Down

[Greg Kroah-Hartman]

From: Ajay Singh <ajay.kathat@xxxxxxxxxxxxx>

[ Upstream commit fcf690b0b47494df51d214db5c5a714a400b0257 ]

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")
