Add support for the following AMIC SPI chips
http://www.amictechnology.com/pdf/A25L20P.pdf covers: AMIC A25L05PT AMIC A25L05PU AMIC A25L10PT AMIC A25L10PU AMIC A25L20PT AMIC A25L20PU http://www.amictechnology.com/pdf/A25L16P.pdf covers: AMIC A25L16PT AMIC A25L16PU Clarify the situation surrounding the A25L40PT and A25L40PU chips which share the same RDID values, despite the fact that their erase block layouts are different. Rudolf Marek tested and confirmed the distinct erase block layouts of these chips. Add a pretty-printer for the AMIC SPI chip status register Add a generic AMIC chip type.
