On HS cores, loop buffer (LPB) is programmable in runtime and can
be optionally disabled.

Changes v1->v2:
* Fallback to ISA default mcpu flag if custom one isn't supported by
compiler.
* Drop HSDK custom Kconfig options (choose between HSDK and HSDK-4xD) as
we don't need it (at least for now). Instead we select ARC_LPB_DISABLE
for both boards but it's totally OK as HSDK doesn
Kernel builds set their own default -mcpu for a given ISA build.
But that gets in the way of "custom" -mcpu flags from propagating
into kernel build.
This will also be used in next patches for HSDK-4xD board support which
uses a different -mcpu to effect dual issue scheduling.

Add documentation for HSDK-4xD board/SoC bindings. While I'm at it
convert HSDK board/SoC bindings to DT schema format using
json-schema.

This initial port adds support of ARC HS4x/HS4xD Development Kit board
with some basic features such serial port, USB, SD/MMC, SPI flash,
Ethernet and others.
The HSDK-4xD board has much in common with its predecessor - HSDK board.
However HSDK-4xD has some differences in comparison with its prede
