wifi: wilc1000: disable power sequencer

Driver systematically disables some power mechanism each time it starts the
chip firmware (so mostly when interface is brought up). This has a negative
impact on some specific scenarios when the chip is exposed as a
hotpluggable SDIO card (eg: WILC1000 SD):
- when executing suspend/resume sequence while interface has been brought
  up
- rebooting the platform while module is plugged and interface has been
  brought up
Those scenarios lead to mmc core trying to initialize again the chip which
is now unresponsive (because of the power sequencer setting), so it fails
in mmc_rescan->mmc_attach_sdio and enter a failure loop while trying to
send CMD5:
mmc0: error -110 whilst initialising SDIO card
mmc0: error -110 whilst initialising SDIO card
mmc0: error -110 whilst initialising SDIO card
[...]

Preventing the driver from disabling this "power sequencer" fixes those
enumeration issues without affecting nominal operations.
