[RFC PATCH 1/2] powerpc/64: drop redundant defination of spin_until_cond

[Sudeep Holla <sudeep.holla@arm.com>]

linux/processor.h has exactly same defination for spin_until_cond.
Drop the redundant defination in asm/processor.h

Hi,

When I was planning to use spin_until_cond, I came across the same defination
at 2 different headers, one of which includes the other and takes care of
enabling the defination in case of undefinded condition.

I found it redundant, but I may be wrong.

Regards,
Sudeep
