wifi: wilc1000: disable SDIO func IRQ before suspend
Issuing a system suspend command raises the following warning: WARNING: CPU: 0 PID: 15 at drivers/mmc/core/sdio.c:1042 mmc_sdio_suspend+0xd4/0x19c CPU: 0 PID: 15 Comm: kworker/u2:1 Not tainted 6.7.0-rc1-wt+ #710 Hardware name: Atmel SAMA5 Workqueue: events_unbound async_run_entry_fn unwind_backtrace from show_stack+0x18/0x1c show_stack from dump_stack_lvl+0x34/0x48 dump_stack_lvl from __warn+0x98/0x160 __warn from warn_slowpath_fmt+0xcc/0x140 warn_slowpath_fmt from mmc_sdio_suspend+0xd4/0x19c mmc_sdio_suspend from mmc_bus_suspend+0x50/0x70 mmc_bus_suspend from dpm_run_callback+0xe4/0x248 dpm_run_callback from __device_suspend+0x234/0x91c __device_suspend from async_suspend+0x24/0x9c async_suspend from async_run_entry_fn+0x6c/0x210 async_run_entry_fn from process_one_work+0x3a0/0x870 [...] This warning is due to a check in SDIO core ensuring that interrupts do not remain enabled for cards being powered down during suspend. WILC driver currently does not set the MMC_PM_KEEP_POWER flag, so disable interrupt when entering resume.
