[PATCH v2] arm: improve non-section-aligned low memory mapping

Fix space errors. In current design, the memblock.current_limit is set to a section-aligned value in sanity_check_meminfo(). However, the section-aligned memblock may become non-section-aligned after arm_memblock_init(). For example, the first section-aligned memblock is 0x-0x0100
