arm64: fixmap: Allow 256K early_ioremap() at any offset
NR_FIX_BTMAPS is the per-slot page limit for early_ioremap(). Since
__early_ioremap() maps the page-aligned physical range, a 256K request
can require one extra page when the physical address is not page-aligned.
Reserve one extra page per slot so the 256K mapping budget is usable
regardless of the initial page offset.
