rtc: pcf8523: Fix GCC 12 warning

Browse Source 
When building with automatic stack variable initialization, GCC 12
complains about variables defined outside of switch case statements.
Move variables outside the switch, which silences warnings:

./drivers/rtc/rtc-pcf8523.c:284:20: error: statement will never be executed [-Werror=switch-unreachable]
  284 |                 u8 mode;
      |

./drivers/rtc/rtc-pcf8523.c:245:21: error: statement will never be executed [-Werror=switch-unreachable]
  245 |                 u32 value;
      |                     ^~~~~
