    nvmem: meson-efuse: fix function pointer type mismatch
    
    [ Upstream commit cbd38332c140829ab752ba4e727f98be5c257f18 ]
    
    clang-16 warns about casting functions to incompatible types, as is done
    here to call clk_disable_unprepare:
    
    drivers/nvmem/meson-efuse.c:78:12: error: cast from 'void (*)(struct clk *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
       78 |                                        (void(*)(void *))clk_disable_unprepare,
    
    The pattern of getting, enabling and setting a disable callback for a
    clock can be replaced with devm_clk_get_enabled(), which also fixes
    this warning.
