Add .editorconfig file ...

The .editorconfig file provides an editor agnostic definition of a
project's file format requirements.
Details can be found at http://editorconfig.org/

This change should have little impact on users, but, it is hoped, will
help those who move across projects avoid making mistakes because of
foreign project editor configuration settings.

css/sgi575: enable ARM_PLAT_MT flag ...

SGI-575 platform is based on Cortex-A75 processor which has its MT bit
in the MPIDR register set to '1'. So the Arm platform layer code has
to be made aware of this.

plat/arm: Add MHUv2 support to SCMI driver ...

Currently the SCMI driver supports MHUv1, but Arm platforms may have
varied versions of MHU driver, with MHUv2 controllers being in the
latest Arm platforms.

This patch updates the SCMI driver to support MHUv2, specifically that
the sender must send the wake-up to the receiver before initiating any
data transfer.

Also, the existing mhu driver files, css_mhu.c and css_mhu.h, have been
moved from the scpi directory to a new directory, css/drivers/mhu.

Check presence of fix for errata 835769 in Cortex-A53 ...

A fix for errata 835769 may be available in revisions r0p2, r0p3 or r0p4
of the Cortex-A53 processor. The presence of the fix is determined by
checking bit 7 in the REVIDR register.

If the fix is present we report ERRATA_NOT_APPLIES which silences the
erroneous 'missing workaround' warning.
