[PATCH -next] mfd: Make symbol 'atc260x_i2c_of_match' static

['Wei Yongjun <weiyongjun1@huawei.com>]

From: Wei Yongjun <weiyongjun1@huawei.com>

The sparse tool complains as follows:

drivers/mfd/atc260x-i2c.c:45:27: warning:
 symbol 'atc260x_i2c_of_match' was not declared. Should it be static?

This symbol is not used outside of atc260x-i2c.c, so this
commit marks it static.

Fixes: f7cb7fe34db9 ("mfd: Add MFD driver for ATC260x PMICs")
