[PATCH -next] regulator: Make symbols static

[Yue Haibing <yuehaibing@huawei.com>]

From: YueHaibing <yuehaibing@huawei.com>

Fix sparse warnings:

drivers/regulator/stm32-pwr.c:35:5: warning:
 symbol 'ready_mask_table' was not declared. Should it be static?
drivers/regulator/stm32-pwr.c:47:5: warning:
 symbol 'stm32_pwr_reg_is_ready' was not declared. Should it be static?
drivers/regulator/stm32-pwr.c:57:5: warning:
 symbol 'stm32_pwr_reg_is_enabled' was not declared. Should it be static?
