Somehow EMSDP & IoT DK boards were skipped on ARC boads conversion
to DM MMC. So doing it now.

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

This allows us to print nice board name on boot.

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.

So now we may detect MMC/SD-card existence and
instead of completely misleading message on missing card:
------------------------>8-----------------------
Loading Environment from FAT... Card did not respond to voltage select!
------------------------>8-----------------------

we now get very clear one:
------------------------>8-----------------------
Loading Environment from FAT... MMC: no card present
------------------------>8-----------------------

Synopsys DesignWare ARC EM Development Kit (ARC EMDK) is
an FPGA-based development platform from Synopsys aimed to speed-up
development of software for ARC EM cores and entire subsystems based on
ARC EM like Data Fusion, Secure and Sensor & Control subsystems.

U-Boot is supposed to be used as a primary bootloader on EMDK allowing
users to easily load and start their application from micro-SD card.
