ARM: use r9 for gd
To be more EABI compliant and as a preparation for building
with clang, use the platform-specific r9 register for gd
instead of r8.
note: The FIQ is not updated since it is not used in u-boot,
and under discussion for the time being.
The following checkpatch warning is ignored:
WARNING: Use of volatile is usually wrong: see
Documentation/volatile-considered-harmful.txt
