[PATCH] nvmem: meson-efuse: fix function pointer type mismatch

[Arnd Bergmann]

From: Arnd Bergmann <arnd at arndb.de>

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,

Address this with a trivial helper function that adjusts the return code.

Fixes: 611fbca1c861 ("nvmem: meson-efuse: add peripheral clock")
