drivers: i2c: stm32: don't manage cache aside DMA support
Fix STM32 I2C driver to not call cache management related functions
when DMA is not used. This change fixes an issue introduced by
commit 42c3a7814810 ("i2c: stm32: Add cache memory support"). The issue
makes boards embedding this driver with both CONFIG_I2C_STM32_V2_DMA
and CONFIG_ARCH_MPU disabled to fail to build with an error trace message
like the below:
.../i2c_ll_stm32_v2.c:701: undefined reference to `mem_attr_check_buf'
