Introduce additional SPI status register helpers.

 - spi_prettyprint_status_register_default_welwip():
   It just prettyprints the plain hex value and the welwip bits.
 - spi_prettyprint_status_register_default_bp4():
   Prints the hex value, welwip, bp0-5 and srwd bits.
 - spi_disable_blockprotect_bp2_srwd(),
 - spi_disable_blockprotect_bp3_srwd() and
   spi_disable_blockprotect_bp4_srwd():
   Three new common block unprotection functions for the frequent
   cases where there is a status register lock bit at bit #7 and some
   block protection bits at bits #2-#4, #2-#5 and #2-#6 respectively.

Fix hwaccess (again).
Add support for AMD Geode's MSR on OpenBSD.

Previously the default implementation was used, which always failed.
On other systems than the Geode the code is not equal to that anymore,
but should not explode because setup_cpu_msr() returns an error and
therefore no other MSR functions should be called.

Various cross-platform fixes.

Improve compilation with libpayload (compiling flashrom.c and
linking is still broken):
 - disable Ponyprog (which enforced serial.c compilation)
 - make errno available where it is needed

Fix internal.c for non-x86 and enable cb parsing on ARM.

Fix mingw builds by using its __USE_MINGW_ANSI_STDIO macro
and gnu_printf definition for printf format style checking.
See http://sourceforge.net/apps/trac/mingw-w64/wiki/gnu%20printf
This requires inclusion of stdio.h in flash.h.

Fix order of libraries in the Makefile:
FEATURE_LIBS needs to come *after* PCILIBS in case ZLIB is needed by it.

 - Removed 10de:03e2 because it is apparently the MCP61 host bridge.
   It was reclassified to Host Bridge in the PCI device ID database and there
   is at least one report suggesting this configuration too:
   http://www.flashrom.org/pipermail/flashrom/2012-August/009716.html

   Thanks to James Laird for submitting this change.

 - Atmel AT25F512 to PREW (+PREW)
   http://www.flashrom.org/pipermail/flashrom/2013-April/010904.html
   Also, change its ID according to Modification of PCN SC040401A:
   "There has been a change in the returned value of the Product Identification
   (RDID) command, the AT25F512A RDID code is 65h compared to 60h from
   the AT25F512 product."
   It seems to be quite likely that all AT25F512 are fully functional relabeled
   AT25F1024 chips. There are even some hints in the datasheet:
   in table 6 they stress that address pin 16 needs to be low under all circum-
   stances; while continuous reads can wrap around on the AT25F1024 the DS
   notes "For the AT25F512, the read command must be terminated when the
   highest address (00FFFF) is reached." OTOH the lock bit semantics are
   different, but this has not been tested thoroughly
