[PATCH -next] regulator: stm32-pwr: Make some symbols static

[Wei Yongjun]

Fixes the following 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?

Fixes: 6cdae8173f67 ("regulator: Add support for stm32 power regulators")
