Without this header, we get a lengthy build error:

drivers/regulator/bd718x7-regulator.c:364:16: error: implicit declaration of function 'of_match_ptr'; did you mean 'hash_ptr'? [-Werror=implicit-function-declaration]
    .of_match = of_match_ptr("BUCK1"),
                ^~~~~~~~~~~~
                hash_ptr

drivers/regulator/bd718x7-regulator.c:364:16: note: (near initialization for 'bd71847_regulators[0].desc.of_match')
