mmc: pwrseq: sd8787: Fix WILC CHIP_EN and RESETN toggling order
Chapter "5.3 Power-Up/Down Sequence" of WILC1000 [1] and WILC3000 [2]
states that CHIP_EN must be pulled HIGH first, RESETN second. Fix the
order of these signals in the driver.
Use the mmc_pwrseq_ops as driver data as the delay between signals is
specific to SDIO card type anyway.
