Subject: [RFC PATCH 4/9] powerpc/Kconfig: Select FUNCTION_ALIGNMENT_4B

From: Sathvika Vasireddy <sv@...ux.ibm.com>

Commit d49a0626216b95 ("arch: Introduce CONFIG_FUNCTION_ALIGNMENT")
introduced a generic function-alignment infrastructure. Move to using
FUNCTION_ALIGNMENT_4B on powerpc, to use the same alignment as that of
the existing _GLOBAL macro.
