[PATCH] regulator: core: fixup regulator_is_equal() helper

[Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

commit b059b7e0ec320 ("regulator: core: Add regulator_is_equal() helper")
added regulator_is_equal() helper.
But it has unneeded ";" if CONFIG_REGULATOR was not defined.
Thus, we will have this error

linux/include/linux/regulator/consumer.h:600:1: error: expected \
identifier or '(' before '{' token
 {
 ^
linux/include/linux/regulator/consumer.h:599:1: warning: \
'regulator_is_equal' declared 'static' but never defined \
[-Wunused-function]
 regulator_is_equal(struct regulator *reg1, struct regulator *reg2);
 ^~~~~~~~~~~~~~~~~~

This patch fixup it.
