[PATCH v2] arch/powerpc: Remove unused cede related functions

[Gautam Menghani]

Remove extended_cede_processor() and its helpers as
extended_cede_processor() has no callers since
commit 48f6e7f6d948("powerpc/pseries: remove cede offline state for CPUs")

Signed-off-by: Gautam Menghani <gautam at linux.ibm.com>

v1 -> v2:
1. Remove helpers of extended_cede_processor()
