rtc: ds3232: avoid unused-const-variable warning

Fix the following warning when CONFIG_I2C is not set but CONFIG_SPI_MASTER
is set.

warning: 'ds3232_pm_ops' defined but not used [-Wunused-const-variable=]

'ds3232_pm_ops' is only used by rtc-ds3232 i2c driver, so move the device
PM callbacks inside #if IS_ENABLED(CONFIG_I2C).
