Even though EM SDP is FPGA-based board and different FPGA
images (known as .bit-files) are awailable for the board still
there's a common subset of options we may rely on for all configs.
These are:
* Normalizer
* Swap instructions
* Simple multiplier
* Barrel-shifter
* Floating-point unit
* Shorter instructions (code density)
This among other improvements allows to compile code with
64-bit divisions, see [1].

If the "Page Mode" is not enabled on the device,
read operations from PSRAM may result in incorrect data.

Instead of "base + offset" define all registers right away
and access them later via direct defines.
Generate bit masks with "BIT" macro.

We do real CPU clock measurement with help of built-in
counters. Thus we may accommodate different real clock values
that appear in different FPA images instead of relying on
something hard-coded in the .dtb.
And while at it make make SDIO base address define
look similar to others with casting to "(void *)".

Real marketing name of the board was recently updated so
to accommodate that change renaming the board and all
related to it.
