Lukasz Majewski 0f9c8c2935 arm: stm32h7: Enable DCache when CONFIG_DCACHE is defined
Up till now the usage of CONFIG_NOCACHE_MEMORY also explicitly disables
data cache on the STM32H7 SoC.

With this change the usage of CONFIG_NOCACHE_MEMORY has been decoupled
from data cache enabling as new Kconfig option - namely
CONFIG_DCACHE is now used to explicitly enable it.

After this change it would be possible to use data cache on STM32H7
with DMA buffers, fragile to cache coherency issues, defined with
'__nocache' attribute.

Such approach would improve the overall STM32H7 performance until the
moment when proper (i.e. in-DMA) buffer cache management is developed.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
