The DTS uses hardware register values directly in pin controller pin
configuration. These are not some IDs or other abstraction layer but
raw numbers used in the registers.
These numbers were previously put in the bindings header to avoid code
duplication and to provide some context meaning (name), but they do not
fit the purpose of bindings. It is also quite confusing to use
constants prefixed with Exynos for other SoC, because there is actually
nothing here in common, except the actual value.
Store the constants in a header next to DTS and use them instead of
bindings.

Adds FSD ufs device node and enable the same for fsd platform.
This also adds the required pin configuration for the same.

Add CPU caches information so that the same is available to
userspace via sysfs. This SoC has 48/32 KB I/D cache for
each CPU cores and 4MB of L2 cache.

The pl330 DMA controller provides number of DMA channels and requests
through its registers, so duplicating this information (with a chance of
mistakes) in DTS is pointless. Additionally the DTS used always wrong
property names which causes DT schema check failures - the bindings
documented 'dma-channels' and 'dma-requests' properties without leading
hash sign.

One compatible is used for the Multi-Core Timer on Tesla FSD SoC, which
is correct but not specific enough. The MCT blocks have different
number of interrupts, so add a second specific compatible to Tesla FSD.
