powerpc/fixmap: Fix the size of the early debug area
[ Upstream commit fdc6edbb31fba76fd25d7bd016b675a92908d81e ]
Commit ("03fd42d458fb powerpc/fixmap: Fix FIX_EARLY_DEBUG_BASE when
page size is 256k") reworked the setup of the early debug area and
mistakenly replaced 128 * 1024 by SZ_128.
Change to SZ_128K to restore the original 128 kbytes size of the area.
