mfd: core: Remove .enable() and .disable() callbacks

Browse Source 
With commit dd77f5fa97d3 ("mfd: Remove toshiba tmio drivers") the last
mfd driver that implements these callbacks is gone and since commit
652719b100 ("w1: remove ds1wm driver") the last user is gone. The
corresponding functions mfd_cell_enable() and mfd_cell_disable() are
also unused (since commit 0ca222c819 ("leds: Remove asic3 driver")).
