[OpenBIOS] [commit] r1242 - trunk/openbios-devel/libopenbios

Log:
OFMEM: remove remaining page size constants and replace with PAGE_SIZE

Since OFMEM was originally based upon the PPC architecture (with 4K page size),
there are still some places that use hardcoded values to calculate alignment.
Replace these with equivalents that use the current architecture PAGE_SIZE.
