staging: wilc1000: pass struct wilc to the functions which use hif_func

This patch passes struct wilc to the functions which use hif_func inside.
The function pointers of wilc_hif_func will pass wilc also in the later
patch. Pass wilc to the functions if necessary.

Flollowings are modified functions.
chip_wakeup
wilc_chip_sleep_manually
chip_allow_sleep
wilc_get_chipid
wilc_unknown_isr_ext
wilc_pllupdate_isr_ext
wilc_sleeptimer_isr_ext
