powerpc/perf: consolidate valid_user_sp -> invalid_user_sp
Merge the 32bit and 64bit version.
Halve the check constants on 32bit.
Use STACK_TOP since it is defined.
Passing is_64 is now redundant since is_32bit_task() is used to
determine which callchain variant should be used. Use STACK_TOP and
is_32bit_task() directly.
This removes a page from the valid 32bit area on 64bit:
#define TASK_SIZE_USER32 (0x0000000100000000UL - (1 * PAGE_SIZE))
#define STACK_TOP_USER32 TASK_SIZE_USER32
Change return value to bool. It is inverted by users anyway.
Change to invalid_user_sp to avoid inverting the return value twice.
