powerpc/mm/book3s64: Fix build error with SPARSEMEM disabled
With CONFIG_SPARSEMEM disabled the below kernel build error is observed.
arch/powerpc/mm/init_64.c:477:38: error: use of undeclared identifier 'SECTION_SIZE_BITS'
CONFIG_MEMORY_HOTPLUG depends on CONFIG_SPARSEMEM and it is more clear
to describe the code dependency in terms of MEMORY_HOTPLUG. Outside
memory hotplug the kernel uses memory_block_size for kernel directmap.
Instead of depending on SECTION_SIZE_BITS to compute the direct map
page size, add a new #define which defaults to 16M(same as existing
SECTION_SIZE)
Fixes: 4d15721177d5 ("powerpc/mm: Cleanup memory block size probing")
