lib: Make log2() available in romstage on ARM, not just x86
On x86, log2() is defined as an inline function in arch/io.h. This is a remnant of ROMCC, and forced us to not include clog2.c in romstage. As a result, romstage on ARM has no log2(). Use the inline log2 only with ROMCC, but otherwise, use the one in clog2.c.
