cbfs_spi: Enable speed logging by default for BIOS_DEBUG

The SPI transfer speed logging in cbfs_spi is super useful, doesn't get
in the way (just adding one line per stage, essentially) and should have
no notable overhead. Let's enable it by default for the BIOS_DEBUG log
level rather than having to recompile to get it.

Also fix an issue with building this code on MIPS due to lack of 64-bit
division primitives. (This means MIPS and arm32 board may display
incorrect results when reading more than 4MB in a single transfer, which
sounds very unlikely.)
